| radiance |
a conserved quantity of energy per unit area, per unit solid angle, and per unit of spectrum bandwidth. Radiances are measured by satellite instruments called radiometers or spectrometers, typically in units of mW / (m2.sr.cm-1), in the infrared portion of the spectrum or in units of W / (m2.sr.um), in the visible portion of the spectrum.
