Dear all,
There have been quite some discussion within HTAP about
surface_emissions and atmosphere_emissions.
My intension was to specify surface_emission which refers to sources
physically located at the Earth surface, like e.g. sea salt emissions.
The term atmosphere_emission refers to sources within the atmosphere.
(Just to clarify: atmosphere_emissions does not specify the dimensions
of the field, it could be 1, 2, or 3 dimensional in space.)
In HTAP, we requested for both a 2d field, the latter obtained from
vertical integration of the 3d field. There was some confusion about the
difference, people thought that surface_emission (2d) was obtained from
vertically integrating the 3d atmosphere_emissions.
However, several of the fields we specified as surface_emissions do also
have atmospheric emissions. Therefore I have transformed
surface_emission to atmosphere_emission in the list of proposed
chemistry & aerosol names on the wiki page. Atmosphere_emissions is the
more general term as it includes surface emissions. In case pure
surface_emissions are needed, a standard_name can be suggested to CF in
a later phase.
In addition, I have updated:
atmosphere_emission_mass_flux_of_secondary_organic_carbon_expressed_as_such_dry_aerosol
changed to
atmosphere_production_mass_flux_of_secondary_organic_carbon_expressed_as_such_dry_aerosol
because SOA is not emitted but chemically produced within the atmosphere
Best regards,
Christiane
