"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."@en . . "accepted"@en . . "2013-06-27 14:07:54.0" . . "2013-06-27 14:07:54.0" . . . "" .
