<br />
'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developed since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of October 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developed on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed of certain standard phrases and forms, following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion by the CF mailing list. Therefore, we (Christiane Textor with input from Martin Schultz, Heinke Hoeck, and Martina Stockhause) try to summarize the current status of work here, in order to highlight the principles and concepts we have developed so far. <br />
<br />
A large quantity of new standard names for chemical species, or for other topics, might be necessary in the future. This potential need has triggered a discussion on more general approaches to standard name construction (Thread "a different (but perhaps unoriginal) approach to standard name construction" launched by Karl Taylor.) <br />
<br />
Four main ideas for the construction of new standard names for chemical species have been discussed so far: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discussion of each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
# Definition of groups of standard names (see below). Automated generation of explicit standard names based on these groups. Submit and accept all possible names, even if some of them might not have a physical meaning.<br />
# Definition of groups of standard names (see below). Automated generation of explicit standard names based on these groups. Experts (possibly from the [http://www.igac.noaa.gov/ACandC.php AC&C model intercomparisons]) review these possible names and eliminate unphysical combinations before submission to and acceptance by the CF community.<br />
<br />
Please note that the discussions of the aerosol and chemisty names in CF should be continued on the CF mailing list, and not on this wiki. The wiki is only used here to summarize the state of such names in CF. The descriptions below could help to converge to the most efficient strategy. (Please note, that [[Modfication of existing CF standard names|Modifications of existing CF standard names]] are suggested, if they do not fit in the general concepts explained below.)<br />
<br />
<br />

<br /><br />
<br />
=LIST OF ACCEPTED STANDARD NAMES FOR AEROSOLS AND CHEMICALS=<br />
<br />
The list of standard names for aerosol ad chemicals accepted by October 29 2008 can be found [[LIST OF CHEMICAL SPECIES AND AEROSOLS|'''here''']].<br />
<br />
=CONSTRUCTION OF STANDARD NAMES FOR AEROSOLS AND CHEMICALS=<br />
<p>Certain <strong>phrases and forms</strong> are used: <br />
*chemical species and aerosols: describe the species<br />
*physical quantity (generic names): describe the property of the species, and determine the unit of the variable<br />
*processes: are used in derivatives of variables (e.g. fluxes): tendency_of_.... due_to_&lt;process&gt; and give the change of the species' property due to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />
<br />
These phrases and forms are combined to obtain the standard names, like for example<br />
&lt;physical_quantity&gt;_of_X_in_&lt;medium<br />
tendency_of_&lt;physical_quantity&gt;_of_X_in_&lt;medium&gt;_due_to_&lt;process&gt;<br />
<br />
The combination of these phrases and names results in <strong>groups</strong> of Standard_Names that are given below. However, not all combinations are possible or reasonable. <br />
<br />
There are some odd names that do not fit in the general concepts. [[Modification of existing CF standard names|Modifications]] are suggested for these names in order to allow for the automatic creation of individual names from groups of CF standard names. </p><br />
<br />
==Phrases and forms==<br />
===Chemical species and aerosols===<br />
These can be chemical species with a defined molar mass (molecules, salts, etc.) or components that do not have a defined molar mass (aerosol, biological species)<br /><br />
Goto to the [[list of chemical species and aerosols]] as of 29 October 2008.<br />

mass_content [kg/m2]<br /><br />
mass_fraction [kg/kg]<br /><br />
mass_concentration [kg/m3]<br /><br />
mole_concentration [mole/m3]<br /><br />
mole_fraction [mole/mole]<br /><br />
moles [moles]<br /><br />
tendency_of_&lt;Z&gt;_due_to_&lt;process&gt; (with Z=physical quantity of component, in units of per s)<br />
<br />
===Processes===<br />
dry_deposition <br /><br />
emission <br /><br />
re_emission <br /><br />
wet_deposition <br /><br />
net_production_and_emission <br /><br />
dry_deposition_into_stomata <br /><br />
&lt;no process=total changes&gt;<br />
<br />
===Medium===<br />
in_air <br /><br />
in_sea_water<br /><br />
in_atmosphere<br /><br />
in_middle_atmosphere<br /><br />
in_troposphere<br /><br />
<br />
<p>or <br />
atmosphere used as a prefix (suggested to be changed)</p><br />
<br />
Please note that 'atmosphere' denotes all phases in the atmosphere and includes for example in_air, in_cloud, in_precipiation, etc.<br><br />
in_air means in the gas phase, a definition if this includes also water vapor (dry_air or wet_air?) would be needed.<br />
<br />
==Groups of Standard_Names for chemicals and aerosols==<br />
<p>The combination of the prases and forms given above results in groups of Standard_Names for chemicals and aerosols: </p><br />

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developed since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of October 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developed on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed of certain standard phrases and forms, following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion by the CF mailing list. Therefore, we (Christiane Textor with input from Martin Schultz, Heinke Hoeck, and Martina Stockhause) try to summarize the current status of work here, in order to highlight the principles and concepts we have developed so far. <br />
<br />
A large quantity of new standard names for chemical species, or for other topics, might be necessary in the future. This potential need has triggered a discussion on more general approaches to standard name construction (Thread "a different (but perhaps unoriginal) approach to standard name construction" launched by Karl Taylor.) <br />
<br />
Four main ideas for the construction of new standard names for chemical species have been discussed so far: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discussion of each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
# Definition of groups of standard names (see below). Automated generation of explicit standard names based on these groups. Submit and accept all possible names, even if some of them might not have a physical meaning.<br />
# Definition of groups of standard names (see below). Automated generation of explicit standard names based on these groups. Experts (possibly from the [http://www.igac.noaa.gov/ACandC.php AC&C model intercomparisons]) review these possible names and eliminate unphysical combinations before submission to and acceptance by the CF community.<br />
<br />
Please note that the discussions of the aerosol and chemisty names in CF should be continued on the CF mailing list, and not on this wiki. The wiki is only used here to summarize the state of such names in CF. The descriptions below could help to converge to the most efficient strategy. (Please note, that [[Modfication of existing CF standard names|Modifications of existing CF standard names]] are suggested, if they do not fit in the general concepts explained below.)<br />

<br />
=CONSTRUCTION OF STANDARD NAMES FOR AEROSOLS AND CHEMICALS=<br />
<p>Certain <strong>phrases and forms</strong> are used: <br />
*chemical species and aerosols: describe the species<br />
*physical quantity (generic names): describe the property of the species, and determine the unit of the variable<br />
*processes: are used in derivatives of variables (e.g. fluxes): tendency_of_.... due_to_&lt;process&gt; and give the change of the species' property due to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />
<br />
These phrases and forms are combined to obtain the standard names, like for example<br />
&lt;physical_quantity&gt;_of_X_in_&lt;medium<br />
tendency_of_&lt;physical_quantity&gt;_of_X_in_&lt;medium&gt;_due_to_&lt;process&gt;<br />
<br />
The combination of these phrases and names results in <strong>groups</strong> of Standard_Names that are given below. However, not all combinations are possible or reasonable. <br />
<br />
There are some odd names that do not fit in the general concepts. [[Modification of existing CF standard names|Modifications]] are suggested for these names in order to allow for the automatic creation of individual names from groups of CF standard names. </p><br />

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developed since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of October 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developed on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed of certain standard phrases and forms, following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion by the CF mailing list. Therefore, we (Christiane Textor with input from Martin Schultz, Heinke Hoeck, and Martina Stockhause) try to summarize the current status of work here, in order to highlight the principles and concepts we have developed so far. <br />
<br />
A large quantity of new standard names for chemical species, or for other topics, might be necessary in the future. This potential need has triggered a discussion on more general approaches to standard name construction (Thread "a different (but perhaps unoriginal) approach to standard name construction" launched by Karl Taylor.) <br />
<br />
Four main ideas for the construction of new standard names for chemical species have been discussed so far: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discussion of each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
# Definition of groups of standard names (see below). Creation of all possible names based on these groups for new individual chemical species or aerosols using an automated procedure, even if some of them might not have a physical meaning.<br />
# Definition of groups of standard names (see below). Creation of all possible names based on these groups for new individual chemical species or aerosols using an automated procedure. Experts (possibly from the [http://www.igac.noaa.gov/ACandC.php AC&C model intercomparisons]) review these possible names and eliminate unphysical combinations before submission to the CF community.<br />
<br />
Please note that the discussions of the aerosol and chemisty names in CF should be continued on the CF mailing list, and not on this wiki. The wiki is only used here to summarize the state of such names in CF. The descriptions below could help to converge to the most efficient strategy. (Please note, that [[Modfication of existing CF standard names|Modifications of existing CF standard names]] are suggested, if they do not fit in the general concepts explained below.)<br />

<p>Certain <strong>phrases and forms</strong> are used: <br />
*chemical species and aerosols: describe the species<br />
*physical quantity (generic names): describe the property of the species, and determine the unit of the variable<br />
*processes: are used in derivatives of variables (e.g. fluxes): tendency_of_.... due_to_&lt;process&gt; and give the change of the species' property due to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />
<br />
These phrases and forms are combined to obtain the standard names, like for example<br />
&lt;physical_quantity&gt;_of_X_in_&lt;medium<br />
tendency_of_&lt;physical_quantity&gt;_of_X_in_&lt;medium&gt;_due_to_&lt;process&gt;<br />
<br />
The combination of these phrases and names results in <strong>groups</strong> of Standard_Names that are given below. However, not all combinations are possible or reasonable. <br />
<br />
There are some odd names that do not fit in the general concepts. [[Modification of existing CF standard names|Modifications]] are suggested for these names in order to allow for the automatic creation of individual names from groups of CF standard names. </p><br />

'''SUGGESTED CHANGES'''<br />
<br /><br />
==Individual names==<br />
(old names in bold)<br />
<p><strong>mass_fraction_ammonium_dry_aerosol_in_air</strong><br /><br />
This should be mass_fraction_OF_ammonium_dry_aerosol_in_air</p><br />
<p><strong>mass_concentration_of_sulfate_aerosol_in_air</strong><br /><br />
This should be mass_concentration_of_sulfate_DRY_aerosol_in_air</p><br />
<p><strong>aerosol_angstrom_exponent<br /><br />
</strong>angstrom_exponent_of_ambien_aerosol_in_air<br /><br />
</p><br />
<p><strong>atmosphere_content_of_sulfate_aerosol</strong><br /><br />
atmosphere_MASS_content_of_sulfate_DRY_aerosol</p><br />
<p><strong>optical_thickness_of_atmosphere_layer_due_to_aerosol</strong><br /><br />
The other optical thickness names are built like this:<br /><br />
atmosphere_optical_thickness_due_to_X<br /><br />
For consistency, I would suggest to change the first name to<br /><br />
atmosphere_layer_optical_thickness_due_to_aerosol<br /><br />
</p><br />
<p><strong>surface_carbon_dioxide_mole_flux</strong><br /><br />
new: I am not sure <br /><br />
tendency_of_moles_of_carbon_dioxide_at_the_surface <br /><br />
tendency_of_moles_of_carbon_dioxide_in_atmosphere_due_to_net_surface_flux</p><br />
<br />
----<br />
<br /><br />
==Medium 'atmosphere'==<br />
<p>The Guidelines for Construction of CF Standard Names <br /><br />
http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines<br /><br />
state for 'atmosphere' under 'Special Phrases':<br /><br />
'atmosphere: <br /><br />
used instead of in_air for quantities which are large-scale rather than local '</p><br />
<p>This is not correct for the chemicals and aerosols. Here in_air is<br /><br />
opposed to in_cloud, in_rain, etc, where as in_atmosphere describes<br /><br />
the whole atmosphere. Therefore in_atmosphere cannot be the same as<br /><br />
in_air </p><br />
<p>In addition, 'atmosphere' is not consistently placed: <br /><br />
tendency_of_atmosphere_mass_content_of_&lt;X&gt;_due_to_&lt;process&gt;<br /><br />
Tendency_of_moles_of_&lt;G&gt;_in_atmosphere<br /><br />
Hence, atmosphere is also used as a prefix. I would suggest to change<br /><br />
this and only use the term in_atmosphere.<br /><br />
</p><br />
<br />
----<br />
<br /><br />
<br />
==position of 'expressed as'==<br />
<p>I would suggest to attach the 'expressed_as' to the quality it refers<br /><br />
to, e.g.<br /><br />
tendency_of_atmosphere_mass_content_of_nox_expressed_as_nitrogen_due_to_emission<br /><br />
In some of the accepted standard names this is however not the case, like<br /><br />
for example in <br /><br />
mole_concentration_of_diatoms_in_sea_water_expressed_as_nitrogen<br /><br />
In this case the Medium is squeezed in. </p><br />
<br />
----<br />
<br /><br />
==aerosol - ambient or dry==<br />
<p>I would suggest to get rid of the term _aerosol_ and replace it by<br /><br />
dry_aerosol or/and ambient_aerosol for the atmosphere to avoid<br /><br />
problems. <br /><br />
</p><br />
<br />
<p> It would probably also be good to explain the meanings of _dry_ and _ambient_ aerosol.</p></div>Christianehttps://wiki.esipfed.org/w/index.php?title=CF_Standard_Names_-_Construction_of_Atmospheric_Chemistry_and_Aerosol_Terms&diff=18842CF Standard Names - Construction of Atmospheric Chemistry and Aerosol Terms2008-11-03T22:59:42Z<p>Christiane: /* Groups of Standard_Names for chemicals and aerosols */</p>

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developed since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of october 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developed on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed by the addition of phrases in certain standard forms and order following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion at the CF mailing list. Therefore, I (Christiane Textor) try to summarize the current status of work here, in order to highlight the principles and concepts we have developed so far. <br />
<br />
A large quantity of new standard names for chemical species might be necessary in the future. This requires the development of a general approach on how to proceed. Four main ideas are discussed at the moment: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discuss each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script, even if some of them might not have a physical meaning.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script. Experts (possibly from the [http://www.igac.noaa.gov/ACandC.php AC&C model intercomparisons]) review these possible names and eliminate unphysical before submission to the CF community.<br />
<br />
Please note that the discussions of the aerosol and chemisty names in CF should be continued on the CF mailing list, and not on this wiki. The wiki is only used here to summarize the state of such names in CF. The descriptions below could help to converge to the most efficient strategy. (Please note, that [[Modfication of existing CF standard names|Modifications of existing CF standard names]] are suggested, if they do not fit in the general concepts explained below.)<br />
<br />
A discussion on a more general approach to standard name construction is under discussion at the moment (Thread "a different (but perhaps unoriginal) approach to standard name construction" launched by Karl Taylor.)<br />

=CONSTRUCTION OF STANDARD NAMES FOR AEROSOLS AND CHEMICALS=<br />
<p>Certain <strong>phrases and forms</strong> are used: <br />
*chemical species and aerosols: describe the species<br />
*physical quantity (generic names): describe the property of the species, and determine the unit of the variable<br />
*processes: are used in derivatives of variables (e.g. fluxes): tendency_of_.... due_to_&lt;process&gt; and give the change of the species' property due to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />
<br />
These phrases and forms are combined to obtain the standard names, like for example<br />
&lt;physical_quantity&gt;_of_X_in_&lt;medium<br />
tendency_of_&lt;physical_quantity&gt;_of_X_in_&lt;medium&gt;_due_to_&lt;process&gt;<br />

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developed since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of october 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developed on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed by the addition of phrases in certain standard forms and order following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion at the CF mailing list. Therefore, I (Christiane Textor) try to summarize the current status of work here, in order to highlight the principles and concepts we have developed so far. <br />
<br />
A large quantity of new standard names for chemical species might be necessary in the future. This requires the development of a general approach on how to proceed. Four main ideas are discussed at the moment: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discuss each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script, even if some of them might not have a physical meaning.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script. Experts (possibly from the [http://www.igac.noaa.gov/ACandC.php AC&C model intercomparisons]) review these possible names and eliminate unphysical before submission to the CF community.<br />
<br />
Please note that the discussions of the aerosol and chemisty names in CF should be continued on the CF mailing list, and not on this wiki. The wiki is only used here to summarize the state of such names in CF. The descriptions below could help to converge to the most efficient strategy. (Please note, that [[Modfication of existing CF standard names|Modifications of existing CF standard names]] are suggested, if they do not fit in the general concepts explained below.)<br />
<br />
A discussion on a more general approach to standard name construction is under discussion at the moment (Thread "a different (but perhaps unoriginal) approach to standard name construction" launched by Karl Taylor.)<br />

=LIST OF ACCEPTED STANDARD NAMES FOR AEROSOLS AND CHEMICALS=<br />
<br />
The list of standard names for aerosol ad chemicals accepted by October 29 2008 can be found [[LIST OF CHEMICAL SPECIES AND AEROSOLS|here]].<br />
<br />
=CONSTRUCTION OF STANDARD NAMES FOR AEROSOLS AND CHEMICALS=<br />
<p>Certain <strong>phrases and forms</strong> are used: <br />
*chemical species and aerosols: describe the species<br />
*physical quantity (generic names): describe the property of the species, and determine the unit of the variable<br />
*processes: are used in derivatives of variables (e.g. fluxes): tendency_of_.... due_to_&lt;process&gt; and give the change of the species' property due to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />
<br />
These phrases and forms are combined to obtain the standard names, like for example<br />
&lt;physical_quantity&gt;_of_X_in_&lt;medium<br />
tendency_of_&lt;physical_quantity&gt;_of_X_in_&lt;medium&gt;_due_to_&lt;process&gt;<br />
<br />
The combination of these phrases and names results in <strong>groups</strong> of Standard_Names that are given below. However, not all combinations are possible or reasonable. <br />
<br />
There are some odd names that do not fit in the general concepts. [[Modification of existing CF standard names|Modifications]] are suggested for these names in order to allow for the automatic creation of individual names from groups of CF standard names. </p><br />
<br />
==Phrases and forms==<br />
===Chemical species and aerosols===<br />
These can be chemical species with a defined molar mass (molecules, salts, etc.) or components that do not have a defined molar mass (aerosol, biological species)<br /><br />

<p>Certain <strong>phrases and forms</strong> are used: <br />
*chemical species and aerosols: describe the species<br />
*physical quantity (generic names): describe the property of the species, and determine the unit of the variable<br />
*processes: are used in derivatives of variables (e.g. fluxes): tendency_of_.... due_to_&lt;process&gt; and give the change of the species' property due to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />
<br />
These phrases and forms are combined to obtain the standard names, like for example<br />
&lt;physical_quantity&gt;_of_X_in_&lt;medium<br />
tendency_of_&lt;physical_quantity&gt;_of_X_in_&lt;medium&gt;_due_to_&lt;process&gt;<br />
<br />
The combination of these phrases and names results in <strong>groups</strong> of Standard_Names that are given below. However, not all combinations are possible or reasonable. <br />

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developed since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of october 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developed on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed by the addition of phrases in certain standard forms and order following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion at the CF mailing list. Therefore, I (Christiane Textor) try to summarize the current status of work here, in order to highlight the principles and concepts we have developed so far. <br />
<br />
A large quantity of new standard names for chemical species might be necessary in the future. This requires the development of a general approach on how to proceed. Four main ideas are discussed at the moment: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discuss each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />

<p>Certain <strong>phrases and forms</strong> are used: <br />
*chemical species and aerosols: describe the species<br />
*physical quantity (generic names): describe the property of the species, and determine the unit of the variable<br />
*processes: are used in derivatives of variables: tendency_of_.... due_to_&lt;process&gt; and give the change of the species' property due to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />
<br />
These phrases and forms are combined to obtain the standard names, like for example<br />
&lt;physical_quantity&gt;_of_X_in_&lt;medium<br />
tendency_of_&lt;physical_quantity&gt;_of_X_in_&lt;medium&gt;_due_to_&lt;process&gt;<br />
<br />
The combination of these phrases and names results in <strong>groups</strong> of Standard_Names that are given below. However, not all combinations are possible or reasonable. <br />
<br />
There are some odd names that do not fit in the general concepts. [[Modification of existing CF standard names|Modifications]] are suggested for these names in order to allow for the automatic creation of individual names from groups of CF standard names. </p><br />

'''SUGGESTED CHANGES'''<br />
<br /><br />
==Individual names==<br />
(old names in bold)<br />
<p><strong>mass_fraction_ammonium_dry_aerosol_in_air</strong><br /><br />
This should be mass_fraction_OF_ammonium_dry_aerosol_in_air</p><br />
<p><strong>mass_concentration_of_sulfate_aerosol_in_air</strong><br /><br />
This should be mass_concentration_of_sulfate_DRY_aerosol_in_air</p><br />
<p><strong>aerosol_angstrom_exponent<br /><br />
</strong>angstrom_exponent_of_ambien_aerosol_in_air<br /><br />
</p><br />
<p><strong>atmosphere_content_of_sulfate_aerosol</strong><br /><br />
atmosphere_MASS_content_of_sulfate_DRY_aerosol</p><br />
<p><strong>optical_thickness_of_atmosphere_layer_due_to_aerosol</strong><br /><br />
The other optical thickness names are built like this:<br /><br />
atmosphere_optical_thickness_due_to_X<br /><br />
For consistency, I would suggest to change the first name to<br /><br />
atmosphere_layer_optical_thickness_due_to_aerosol<br /><br />
</p><br />
<p><strong>surface_carbon_dioxide_mole_flux</strong><br /><br />
new: I am not sure <br /><br />
tendency_of_moles_of_carbon_dioxide_at_the_surface <br /><br />
tendency_of_moles_of_carbon_dioxide_in_atmosphere_due_to_net_surface_flux</p><br />
<br />
----<br />
<br /><br />
==Medium 'atmosphere'==<br />
<p>The Guidelines for Construction of CF Standard Names <br /><br />
http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines<br /><br />
state for 'atmosphere' under 'Special Phrases':<br /><br />
'atmosphere: <br /><br />
used instead of in_air for quantities which are large-scale rather than local '</p><br />
<p>This is not correct for the chemicals and aerosols. Here in_air is<br /><br />
opposed to in_cloud, in_rain, etc, where as in_atmosphere describes<br /><br />
the whole atmosphere. Therefore in_atmosphere cannot be the same as<br /><br />
in_air </p><br />
<p>In addition, 'atmosphere' not consistently placed: <br /><br />
tendency_of_atmosphere_mass_content_of_&lt;X&gt;_due_to_&lt;process&gt;<br /><br />
Tendency_of_moles_of_&lt;G&gt;_in_atmosphere<br /><br />
Hence, atmosphere is also used as a prefix. I would suggest to change<br /><br />
this and only use the term in_atmosphere.<br /><br />
</p><br />
<br />
----<br />
<br /><br />
==position of 'expressed as'==<br />
<p>I would suggest to attach the 'expressed_as' to the quality it refers<br /><br />
to, e.g.<br /><br />
tendency_of_atmosphere_mass_content_of_nox_expressed_as_nitrogen_due_to_emission<br /><br />
In some of the accepted standard names this is however not the case, like<br /><br />
for example in <br /><br />
mole_concentration_of_diatoms_in_sea_water_expressed_as_nitrogen<br /><br />
In this case the Medium is squeezed in. </p><br />
<br />
----<br />
<br /><br />
==aerosol - ambient or dry==<br />
<p>I would suggest to get rid of the term _aerosol_ and replace it by<br /><br />
dry_aerosol or/and ambient_aerosol for the atmosphere to avoid<br /><br />
problems. <br /><br />
</p><br />
<br />
<p> It would probably also be good to explain the meanings of _dry_ and _ambient_ aerosol.</p></div>Christianehttps://wiki.esipfed.org/w/index.php?title=CF_Standard_Names_-_Construction_of_Atmospheric_Chemistry_and_Aerosol_Terms&diff=18829CF Standard Names - Construction of Atmospheric Chemistry and Aerosol Terms2008-11-03T22:28:23Z<p>Christiane: /* CONSTRUCTION OF STANDARD NAMES FOR AEROSOLS AND CHEMICALS */</p>

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developed since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of october 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developed on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed by the addition of phrases in certain standard forms and order following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion at the CF mailing list. Therefore, I (Christiane Textor) try to summarize the current status of work here, in order to highlight the principles and concepts we have developed so far. <br />
<br />
A large quantity of new standard names for chemical species might be necessary in the future. This requires the development of a general approach on how to proceed. Four main ideas are discussed at the moment: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discuss each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script, even if some of them might not have a physical meaning.<br />

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developed since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of october 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developed on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed by the addition of phrases in certain standard forms and order following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion at the CF mailing list. Therefore, I (Christiane Textor) try to summarize the current status of work here, in order to highlight the principles and concepts we have developed so far. <br />
<br />
A large quantity of new standard names for chemical species might be necessary in the future. This requires the development of a general approach on how to proceed. Four main ideas are discussed at the moment: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discuss each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script, even if some of them might not have a physical meaning.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script. Experts (possibly from the [http://www.igac.noaa.gov/ACandC.php AC&C model intercomparisons]) review these possible names and eliminate unphysical before submission to the CF community.<br />
<br />
Please note that the discussions of the aerosol and chemisty names in CF should be continued on the CF mailing list, and not on this wiki. The wiki is only used here to summarize the state of such names in CF. The descriptions below could help to converge to the most efficient strategy. (Please note, that [[Modfication of existing CF standard names|Modifications of existing CF standard names]] are suggested, if they do not fit in the general concepts explained below.)<br />
<br />
A discussion on a more general approach to standard name construction is under discussion at the moment (Thread "a different (but perhaps unoriginal) approach to standard name construction" launched by Karl Taylor.)<br />

<p>Certain <strong>phrases and forms</strong> ure used: <br />
*chemical species and aerosols: describe the species<br />
*generic names: describe the property of the species, and determinethe unit of the variable<br />
*processes: are used in flux variables: tendency_of_.... due_to_&lt;process&gt; and give the change of the species' property du to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developed since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of october 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developed on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed by the addition of phrases in certain standard forms and order following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion at the CF mailing list. Therefore, I (Christiane Textor) try to summarize the current status of work here, in order to highlight the principles and concepts we have developed so far. <br />
<br />
A large quantity of new standard names for chemical species might be necessary in the future. This requires the development of a general approach on how to proceed. Four main ideas are discussed at the moment: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discuss each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script, even if some of them might not have a physical meaning.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script. Experts (possibly from the [http://www.igac.noaa.gov/ACandC.php AC&C model intercomparisons]) review these possible names and eliminate unphysical before submission to the CF community.<br />
<br />
Please note that the discussions of the aerosol and chemisty names in CF should be continued on the CF mailing list, and not on this wiki. The wiki is only used here to summarize the state of such names in CF. The descriptions below could help to converge to the most efficient strategy. (Please note, that [[Modfication of existing CF standard names|Modifications of existing CF standard names]] are suggested, if they do not fit in the general concepts explained below.)<br />
<br />
A discussion on a more general approach to standard name construction is under discussion at the moment (Thread "a different (but perhaps unoriginal) approach to standard name construction" launched by Karl Taylor.)<br />

<p>Certain <strong>phrases and forms</strong> ure used: <br />
*chemical species and aerosols: describe the species<br />
*generic names: describe the property of the species, and determinethe unit of the variable<br />
*processes: are used in flux variables: tendency_of_.... due_to_&lt;process&gt; and give the change of the species' property du to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developped since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of october 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developped on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed by the addition of phrases in certain standard forms and order following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion at the CF mailing list. Therefore, I (Christiane Textor) try to summarize the current status of work here, in order to highlight the principles and concepts we have devolopped so far. <br />
<br />
A large quantity of new standard names for chemical species might be necessary in the future. This requires the development of a general approach on how to proceed. Four main ideas are discussed at the moment: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discuss each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script, even if some of them might not have a physical meaning.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script. Experts (possibly from the [http://www.igac.noaa.gov/ACandC.php AC&C model intercomparisons]) review these possible names and eliminate unphysical before submission to the CF community.<br />
<br />
Please note that the discussions of the aerosol and chemisty names in CF should be continued on the CF mailing list, and not on this wiki. The wiki is only used here to summarize the state of such names in CF. The descriptions below could help to converge to the most efficient strategy. (Please note, that [[Modfication of existing CF standard names|Modifications of existing CF standard names]] are suggested, if they do not fit in the general concepts explained below.<br />
<br />
A discussion on a more general approach to standard name construction is under discussion at the moment (Thread "a different (but perhaps unoriginal) approach to standard name construction" launched by Karl Taylor.)<br />

<p>Certain <strong>phrases and forms</strong> ure used: <br />
*chemical species and aerosols: describe the species<br />
*generic names: describe the property of the species, and determinethe unit of the variable<br />
*processes: are used in flux variables: tendency_of_.... due_to_&lt;process&gt; and give the change of the species' property du to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />

==Medium 'atmosphere'==<br />
<p>The Guidelines for Construction of CF Standard Names <br /><br />
http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines<br /><br />
state for 'atmosphere' under 'Special Phrases':<br /><br />
'atmosphere: <br /><br />
used instead of in_air for quantities which are large-scale rather than local '</p><br />
<p>This is not correct for the chemicals and aerosols. Here in_air is<br /><br />
opposed to in_cloud, in_rain, etc, where as in_atmosphere describes<br /><br />
the whole atmosphere. Therefore in_atmosphere cannot be the same as<br /><br />
in_air </p><br />
<p>In addition, 'atmosphere' not consistently placed: <br /><br />
tendency_of_atmosphere_mass_content_of_&lt;X&gt;_due_to_&lt;process&gt;<br /><br />
Tendency_of_moles_of_&lt;G&gt;_in_atmosphere<br /><br />
Hence, atmosphere is also used as a prefix. I would suggest to change<br /><br />
this and only use the term in_atmosphere.<br /><br />
</p><br />
<br />
----<br />
<br /><br />
==position of 'expressed as'==<br />
<p>I would suggest to attach the 'expressed_as' to the quality it refers<br /><br />
to, e.g.<br /><br />
tendency_of_atmosphere_mass_content_of_nox_expressed_as_nitrogen_due_to_emission<br /><br />
In some of the accepted standard names this is however not the case, like<br /><br />
for example in <br /><br />
mole_concentration_of_diatoms_in_sea_water_expressed_as_nitrogen<br /><br />
In this case the Medium is squeezed in. </p><br />
<br />
----<br />
<br /><br />
==aerosol - ambient or dry==<br />
<p>I would suggest to get rid of the term _aerosol_ and replace it by<br /><br />
dry_aerosol or/and ambient_aerosol for the atmosphere to avoid<br /><br />
problems. <br /><br />
</p><br />
<br />
<p> It would probably also be good to explain the meanings of _dry_ and _ambient_ aerosol.</p></div>Christianehttps://wiki.esipfed.org/w/index.php?title=CF_Standard_Names_-_Accepted_names_for_aerosols_and_chemistry&diff=18815CF Standard Names - Accepted names for aerosols and chemistry2008-11-03T18:19:00Z<p>Christiane: </p>

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developped since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of october 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developped on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed by the addition of phrases in certain standard forms and order following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion at the CF mailing list. Therefore, I try to summarize the current status of work here, in order to highlight the principles and concepts we have devolopped so far. <br />
<br />
A large quantity of new standard names for chemical species might be necessary in the future. This requires the development of a general approach on how to proceed. Four main ideas are discussed at the moment: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discuss each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script, even if some of them might not have a physical meaning.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script. Experts (possibly from the [http://www.igac.noaa.gov/ACandC.php AC&C model intercomparisons]) review these possible names and eliminate unphysical before submission to the CF community.<br />
<br />
Please note that the discussions of the aerosol and chemisty names in CF should be continued on the CF mailing list, and not on this wiki. The wiki is only used here to summarize the state of such names in CF. The descriptions below could help to converge to the most efficient strategy.<br />

<p>Certain <strong>phrases and forms</strong> ure used: <br />
*chemical species and aerosols: describe the species<br />
*generic names: describe the property of the species, and determinethe unit of the variable<br />
*processes: are used in flux variables: tendency_of_.... due_to_&lt;process&gt; and give the change of the species' property du to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />
<br />
The combination of these phrases and names results in <strong>groups</strong> of Standard_Names that are given below. However, not all combinations are possible or reasonable. <br />
<br />
There are some odd names that do not fit in the general concepts. [[Modfication of existing CF standard names|Modifications]] are suggested for these names in order to allow for the automatic creation of individual names from groups of CF standard names. </p><br />

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developped since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of october 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developped on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed by the addition of phrases in certain standard forms and order following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion at the CF mailing list. Therefore, I try to summarize the current status of work here, in order to highlight the principles and concepts we have devolopped so far. <br />
<br />
A large quantity of new standard names for chemical species might be necessary in the future. This requires the development of a general approach on how to proceed. Four main ideas are discussed at the moment: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discuss each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script, even if some of them might not have a physical meaning.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script. Experts (possibly from the [http://www.igac.noaa.gov/ACandC.php AC&C model intercomparisons]) review these possible names and eliminate unphysical before submission to the CF community.<br />
<br />
The descriptions below could help to converge to the most efficient strategy. <br />

<br />
=CONSTRUCTION OF STANDARD NAMES FOR AEROSOLS AND CHEMICALS=<br />
<p>Certain <strong>phrases and forms</strong> ure used: <br />
*chemical species and aerosols: describe the species<br />
*generic names: describe the property of the species, and determinethe unit of the variable<br />
*processes: are used in flux variables: tendency_of_.... due_to_&lt;process&gt; and give the change of the species' property du to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />
<br />
The combination of these phrases and names results in <strong>groups</strong> of Standard_Names that are given below. However, not all combinations are possible or reasonable. <br />
<br />
There are some odd names that do not fit in the general concepts. [[Modfication of existing CF standard names|Modifications]] are suggested for these names in order to allow for the automatic creation of individual names from groups of CF standard names. </p><br />

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developped since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of october 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developped on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed by the addition of phrases in certain standard forms and order following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion at the CF mailing list. Therefore, I try to summarize the current status of work here, in order to highlight the principles and concepts we have devolopped so far. <br />
<br />
A large quantity of new standard names for chemical species might be necessary in the future. This requires the development of a general approach on how to proceed. Four main ideas are discussed at the moment: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discuss each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script, even if some of them might not have a physical meaning.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script. Experts (possibly from the [http://www.igac.noaa.gov/ACandC.php AC&C model intercomparisons]) review these possible names and eliminate unphysical before submission to the CF community.<br />
<br />
The descriptions below could help to converge to the most efficient strategy. <br />

<p>Certain <strong>phrases and forms</strong> ure used: <br />
*chemical species and aerosols: describe the species<br />
*generic names: describe the property of the species, and determinethe unit of the variable<br />
*processes: are used in flux variables: tendency_of_.... due_to_&lt;process&gt; and give the change of the species' property du to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />
<br />
The combination of these phrases and names results in <strong>groups</strong> of Standard_Names that are given below. However, not all combinations are possible or reasonable. <br />

There are some odd names that do not fit in the general concepts. [[Modfication of existing CF standard names|Modifications]] are suggested for these names in order to allow for the automatic creation of individual names from groups of CF standard names. </p><br />

The [http://www.cgd.ucar.edu/cms/eaton/cf-metadata/index.html NetCDF Climate and Forecast (CF) Metadata Convention] are designed to promote the processing and sharing of files created with the netCDF API. The CF conventions define metadata that provide a definitive description of what the data in each variable represents, and of their spatial and temporal properties. This enables users of data from different sources to decide which quantities are comparable, and facilitates building applications with powerful extraction, regridding, and display capabilities. <br />

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developped since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of october 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developped on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed by the addition of phrases in certain standard forms and order following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion at the CF mailing list. Therefore, I try to summarize the current status of work here, in order to highlight the principles and concepts we have devolopped so far. <br />
<br />
A large quantity of new standard names for chemical species might be necessary in the future. This requires the development of a general approach on how to proceed. Four main ideas are discussed at the moment: <br />
<br />
# Definition of each chemically related standard name explicitly in the CF standard name list, and discuss each of these names individually (current approach).<br />
# Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script, even if some of them might not have a physical meaning.<br />
# Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script. Experts review these possible names and eliminate unphysical before submission to the CF community.<br />
<br />
The descriptions below could help to converge to the most efficient strategy. <br />

<p>Certain <strong>phrases and forms</strong> ure used: <br />

'''This page provides the basis for the construction of CF standard names for atmospheric chemistry and aerosols.'''<br />
<br />
The concepts described here have been developped since May 2006 for the definition of the 207 standard names that are accepted by the CF community as of october 2008.<br />
<br />
The construction of CF standard names for aerosols and chemicals originated in the work of the PRISM project (Peter van Velthoven) see [http://proj.prism.enes.org/Results/Documents/WPs/WP4a/PRISM_standard_name_tables.html PRISM Standard Name Tables], latest Version, V 1.3. They have then been further developped on this wiki page and within the CF-mailing list. Important contributions come from the participating model intercomparison projects listed on the [[Air Quality/Chemistry Naming Conventions|entry page]]. <br />
<br />
The CF web site provides general [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/guidelines Guidelines for Construction of CF Standard Names]. The CF standard names for aerosols and chemicals are composed by the addition of phrases in certain standard forms and order following these guidelines. The concept is explained below in section 2.<br />
<br />
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion at the CF mailing list. Therefore, I try to summarize the current status of work here, in order to highlight the principles and concepts we have devolopped so far. <br />
<br />
A large quantity of new standard names for chemical species might be necessary in the future. This requires the development of a general approach on how to proceed. Three and a half main ideas are discussed at the moment: <br />
<br />
* Definition of each chemically related standard name explicitly in the CF standard name list, and discuss each of these names individually (current approach).<br />
* Definition of groups of standard names (see below) with the individual chemical species or aerosol type given as a scalar coordinate. Names for individual species would not appear any more as CF standard names. Unphysical names would not occur, but the names would not be as human-understandable any more.<br />
* Definition of groups of standard names (see below). Creation of all possible names from these for new individual chemical species or aerosols using a script, even if some of them might not have a physical meaning - OR - Experts review the possible names and eliminate unphysical before submission to the CF community.<br />
<br />
The descriptions below could help to converge to the most efficient strategy. <br />

<br />
=LIST OF ACCEPTED STANDARD NAMES FOR AEROSOLS AND CHEMICALS=<br />
<br />
The list of standard names for aerosol ad chemicals accepted by October 29 2008 can be found [[LIST OF CHEMICAL SPECIES AND AEROSOLS|here]].<br />
<br />
=CONSTRUCTION OF STANDARD NAMES FOR AEROSOLS AND CHEMICALS=<br />
<p>Certain <strong>phrases and forms</strong> ure used: <br />
*chemical species and aerosols: describe the species<br />
*generic names: describe the property of the species, and determinethe unit of the variable<br />
*processes: are used in flux variables: tendency_of_.... due_to_&lt;process&gt and give the change of the species' property du to a certain process<br />
*medium: indicates the local medium or layer within which the variable applies<br />
<br />
The combination of these phrases and names results in <strong>groups</strong> of Standard_Names that are given below. However, not all combinations are possible or reasonable. <br />
<br />
There are some odd names that do not fit in the general concepts. [[Modfication of existing CF standard names|Modifications]] are suggested for these names in order to allow for the automatic creation of individual names from groups of CF standard names. </p><br />
