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. 

This wiki is an ''ad hoc'' virtual workgroup effort created in 2006 in order to construct new CF standard_names for air chemistry and aerosols, which will then be submitted to the [[http://www.cgd.ucar.edu/mailman/listinfo/cf-metadata CF mailing list]] for approval.
The wiki is coordinated by [[User:ChristianeTextor|ChristianeTextor]] and involves many other [[CFpeople|people]], and more!.

The CF convention has been adopted for chemicals and aerosols by the following model intercomparisons (state of July 2008): <br>
* [http://www.htap.org/ Task Force on Hemispheric Transport of Air Pollution (TF HTAP)] 
* [http://www.pa.op.dlr.de/CCMVal/ SPARC Chemistry-Climate Model Validation Activity (CCMVal)]
* [http://www.igac.noaa.gov/ACandC.php IGAC-SPARC Atmospheric Chemistry & Climate Initiative (AC&C)]  
* [http://nansen.ipsl.jussieu.fr/AEROCOM/aerocomhome.html AeroCom]

Since 2006 standard names for many species and parameters have been defined (207 in July 2008), see [http://cf-pcmdi.llnl.gov/documents/cf-standard-names/9/cf-standard-name-table.html CF table of standard names, choose "Atmospheric Chemistry"]. 

New standard_names are defined through a step-wise procedure, see [http://cf-pcmdi.llnl.gov/ the CF conventions web site]. 
At the moment, many new proposals for standard names for aerosols and chemicals are under discussion at the CF mailing list. This requires the development of a general approach on how to proceed. See [[CF Standard Names - Construction of Atmospheric Chemistry and Aerosol Terms|Construction of Atmospheric Chemistry and Aerosol Terms]] for further discussion.

==How the wiki works== 
* Every '''article''' page has an associated '''discussion/talk''' page. Links to are provided above.
* On top of each page a menu allows to move between '''article''' and '''discussion'''. In addition, the wiki keeps track and allows recalling all previous versions through the '''history'''-tab.
* The discussion-page associated with an article is titled Talk:<article name>.
* To move between the pages, use the top-menu or the links on the pages. DO NOT USE THE MENU BAR ON THE LEFT HAND SIDE.
* Each '''article''' and '''discussion''' can be edited by any participant. Click to learn [[How to edit the wiki |'''how to edit the wiki''']]!
* [[Workspace:=Interoperability]] [[Category:WS:Workspace]][[WS::{{PAGENAMEE}}]]
