It does not mean \"net downward\". The sign convention is that \"upwelling\" is positive upwards and \"downwelling\" is positive downwards. Photon radiance is the photon flux in a particular direction, per unit of solid angle. The direction from which it is coming must be specified, for instance with a coordinate of zenith_angle. If the radiation does not depend on direction, a standard name of isotropic radiance should be chosen instead. A photon flux is specified in terms of numbers of photons expressed in moles. A coordinate variable for radiation wavelength should be given the standard name radiation_wavelength."@en ; skos:notation "SDN:P07::Z2CRG5G5" ; skos:note "accepted"@en ; skos:prefLabel "downwelling_photon_radiance_per_unit_wavelength_in_sea_water"@en ; skos:related .
