Revision as of 09:33, June 30, 2006
Go back to Forum, Resources and Discussion on CF compliant Atmospheric Chemistry and Aerosol Names
This page provides our ideas on how to construct new names for chemistry and aerosols in the future.
For the standard_names actually proposed to the CF convention see Proposed Atmospheric Chemistry and Aerosol Names
UNFINISHED - WORK IN PROGRESS Version update
- first version 22 May 2006
- updated 2 June 2006 Christiane Textor
- updated 8 June 2006 Christiane Textor
- updated 12 June 2006 Michael Schulz
- updated 13 June 2006 Christiane Textor

Comments to ChristianeTextor or directly on our discussion page are highly welcome!
You can directly modify the tables here, all versions are stored under 'history'. However, in order to keep track of the changes, please send an email to ChristianeTextor.
The ideas in these table are based on work in the PRISM project (Peter van Velthoven) see PRISM Standard Name Tables, latest Version, V 1.3
Table 1 provides the name-components and terms to be used in constructing CF names for Atmospheric Chemistry and Aerosol purposes.
Tables 2 add a list of chemical and aerosol species to be used together with the name components given in table 1.
Tables 3 provide a list of most often used standard names, constructed solely from name components and species already mentioned in tables 1 and 2.
Table 1: Components to construct full CF standard names
Several types of Name-components exist: 1) Compartments; 2) Interface or Origin information; 3) Concentration/mixing ratio/column burden; 4) Fluxes; 5) Optical properties
Missing:
- all forcing variables are still missing
- always provide also in_air = atmosphere (as opposed to ocean,soil) info in names?
- how to distinguish ion - radicals, e.g. NO3 ?
Remarks:
- articles and prepositions should be avoided
- try to use SI units (e.g. not hours but seconds)
- atmosphere_optical_thickness_due_to_X
is defined by CF, however: 1) very long name, 2) does not fit with cloud_optical_depth, 3) is there any opt. depth not in the atmosphere? therefore suggestion of this new name/alias"
