Dear Beate and Ronny Thanks for your proposals.

I think there is a problem with "downwelling", which like "downward" refers in standard names to a vertical component. Would it be reasonable to call this quantity surface_direct_solar_irradiance_in_air The existing definition of solar_irradiance says that it applies only outside the atmosphere, but the concept is the same, meaning the radiative flux along the direction of the beam. Alternatively, perhaps we could replace "downwelling" with "along_beam" or something like that. I feel that "normalized" isn't such a good word, since it could mean many possible things. > 2. > Analog to atmosphere_mass_content_of_cloud_liquid_water we want to apply > for two new standard names: atmosphere_mass_content_of_rainwater and > atmosphere_mass_content_of_snow. I think atmosphere_mass_content_of_snow is OK, but I would propose atmosphere_mass_content_of_rain for the other, since we already have e.g. mass_fraction_of_rain_in_air. > The standard name air_potential_temperature is misleading because the > description refers to air and sea water. > We recommend replacing the standard name by potential_temperature. I disagree with that. When a similar property is measured in a different medium, we have a distinct standard name for it, e.g. air_temperature vs sea_ice_temperature, mole_concentration_of_dimethyl_sulfide_in_air vs mole_concentration_of_dimethyl_sulfide_in_sea_water.
