| Note | see e.g. mass_concentration_of_absorption_equivalent_black_carbon_of_pm10_dry_aerosol_particles_in_air in cf standard names. The term 'Mass concentration' already exists but the definition, sampling media and the compartment is to specific and has to be expanded to Air and atmosphere at least |
