Dear all,
some time ago was discussed the definition of additional inherent optical properties, namely (with a minor correction): volume_backwards_scattering_coefficient_of_radiative_flux_in_sea_water_due_t o_particles (volume_backwards_scattering_coefficient_of_radiative_flux_in_sea_water already exists). volume_absorption_coefficient_of_radiative_flux_in_sea_water_due_to_phytopla nkton ( volume_absorption_coefficient_of_radiative_flux_in_sea_water already exists). volume_absorption_coefficient_of_radiative_flux_in_sea_water_due_to_dissolve d_organic_matter_and_non_pigmented_particles ( volume_absorption_coefficient_of_radiative_flux_in_sea_water_due_to_dissolve d_organic_matter already exists). and for completeness: volume_absorption_coefficient_of_radiative_flux_in_sea_water_due_to_non_pigm ented_particles Would it be possible to have them included in the next update in case there is no objection? Additionally I would like to have the following names considered: mass_concentration_of_particulate_matter_in_sea_water mass_concentration_of_particulate_inorganic_matter_in_sea_water There are already several mole_concentration_of_particulate(_organic)_matter_expressed_as _in_sea_wate r in the list but these ones are missing.

The definition of the existing names says that they are assumed to be an integral over all wavelengths unless the wavelength range is specified, which can be done by adding a scalar or size-1 coordinate variable with standard_name of radiation_wavelength. The bounds of this coordinate variable would contain the wavelength range. However it would be appropriate to insert "spectral" into the standard name if the quantity is actually per unit wavelength. In that case the unit would be m-2 (i.e. volume absorption/scattering coeff in m-1, per unit wavelength range in m).
