Record 2 2007-01-31

English

Subject field(s)
  • Space Physics
  • Remote Sensing
DEF

The capacity of a material to absorb incident radiant energy.

CONT

Absorptivity of a surface is the fraction of radiant energy incident which is absorbed. It is numerically equal to the emissivity for any given surface.

OBS

absorptivity: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

French

Domaine(s)
  • Physique spatiale
  • Télédétection
DEF

Capacité d'un milieu à absorber l'énergie rayonnante.

CONT

À l'équilibre thermodynamique, l'émissivité est égale à l'absorptivité qui représente la fraction de puissance incidente à la surface de la mer qui est absorbée.

OBS

absorptivité : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

Spanish

Campo(s) temático(s)
  • Física espacial
  • Teledetección
DEF

Razón entre la radiación térmica absorbida por una superficie y la que incide sobre ella.

CONT

En equilibrio termodinámico, la emisividad de un cuerpo o superficie es igual a su absorbencia.
