Goto the the list of HTAP Proposed Atmospheric Chemistry and Aerosol Names


The standard_names listed on this page are used within model intercomparison within the Task Force on Hemispheric Transport of Air Pollution TF HTAP. However, as the simulations already started before the names have been officially approved by CF, some minor changes will be necessary.
