The sign convention is that \"upwelling\" is positive upwards and \"downwelling\" is positive downwards. A coordinate variable for radiation wavelength should be given the standard name radiation_wavelength. Radiance is the radiative 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."@en . "SDN:P07::6151973H" .
