| Definition | Radiance is the radiative flux in a particular direction, per unit of solid angle. If radiation is isotropic, the radiance is independent of direction, so the direction should not be specified. If the radiation is directionally dependent, a standard name of upwelling or downwelling radiance should be chosen instead. A coordinate variable for radiation wavelength should be given the standard name radiation_wavelength. | ||
