Version 1: 20.12.2006

This table gives a list of variables that have been accepted by the CF community CF mailing list.

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.

CF Standard_name Canonical unit Explanation
dry deposition flux at the surface
surface_dry_deposition_mass_flux_of_all_nitrogen_oxides_expressed_as_nitrogen kg m-2 s-1 NOy is the sum of all simulated oxidized nitrogen species, out of NO, NO2, HNO3, HNO4, NO3aerosol, NO3(radical), N2O5, PAN, other organic nitrates. Dry deposition includes gravitational settling, impact scavenging, and turbulent deposition"
stomatal flux
surface_wet_deposition_mass_flux_of_all_nitrogen_oxides_expressed_as_nitrogen kg m-2 s-1 NOy is the sum of all simulated oxidized nitrogen species, out of NO, NO2, HNO3, HNO4, NO3aerosol, NO3(radical), N2O5, PAN, other organic nitrates
