LUMINANCE ATMOSPHERIQUE [1 record]

Record 1 2007-01-31

English

Subject field(s)
  • Geophysics
  • Atmospheric Physics
DEF

The radiant flux per unit solid angle per unit of projected area of the source in the atmosphere.

CONT

The atmospheric radiance is collected by the front-end optics (mainly steering mirrors and a telescope) and directed to the Michelson interferometer which allows to measure broadband spectra with a very good spectral resolution. The second input port to the interferometer is closed with a cold blackbody to suppress disturbing radiance.

French

Domaine(s)
  • Géophysique
  • Physique de l'atmosphère
DEF

Flux émis par unité de surface projetée et par unité d'angle solide de la source dans l'atmosphère.

CONT

La radiance marine étant obtenue par soustraction de la radiance atmosphérique de la radiance totale, une surestimation de la composante atmosphérique a pour effet de sous-estimer la radiance marine ; ce qui est particulièrement apparent aux courtes longueurs d'onde.
