English

Subject field(s)
  • Atmospheric Physics
  • Scientific Measurements and Analyses
DEF

Parameter (dlambda) equal to the logarithm of the ratio of the flux (I0lambda) of light with wavelength ([lambda]) incident on a cloud to the flux (Ilambda) emerging from it, characterizing the degree to which the cloud allows this light to pass: dlambda = log10I0lambda/Ilambda.

French

Domaine(s)
  • Physique de l'atmosphère
  • Mesures et analyse (Sciences)
DEF

Paramètre (dlambda) égal au logarithme du rapport du flux de lumière (I0lambda) de longueur d'onde ([lambda]) incident sur un nuage au flux émergeant (Ilambda) du nuage [...]

OBS

[...] il caractérise la mesure dans laquelle ce nuage laisse traverser cette lumière : dlambda = log10I0lambda/Ilambda.
