Christiane Textor, July 2007



It is the philosophy of CF only define those standard_names for which a demand has been expressed. The proposed standard_names on this page are needed for a model intercomparison of three CTMs within the Global and regional Earth-system (Atmosphere) Monitoring using Satellite and in-situ data GEMS project within the theme Global Reactive Gases (GRG). In addition, most of these names probably will be needed within the Task Force on Hemispheric Transport of Air Pollution TF HTAP.

The proposed standard_names listed below are based on the ideas provided at Construction of Atmospheric Chemistry and Aerosol Terms and Future Standard_Names. They are constructed from name components and species mentioned in tables 1 and 2 of this page.


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.
