Go back to Start page for Atmospheric Chemistry and Aerosol Names PLEASE DO NOT USE THE NAVIGATION BAR ON THE LEFT HAND SIDE!
The proposed standard_names 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.
