Subject field(s)
  • Electromagnetic Radiation
  • Atmospheric Physics
  • Space Physics
DEF

... a measure of radiometric flux density per unit solid angle.

OBS

Unlike irradiance, radiance is a property solely of a radiation field, not of the orientation of the surface. ... In general, radiance depends on time, position, and direction as well as frequency (monochromatic or spectral radiance) or range of frequencies.

OBS

Do not confuse "radiance" with "luminance" which is the photometric equivalent of radiance and is expressed in candelas per square meter (cd/m²).

OBS

Standard units of radiance are watts per square meter and steradian: W . m-2. sr-1 or W/(m².sr).

OBS

radiance: term officially approved by the RADARSAT-2 Terminoology Approval Group (RTAG).
