QUE SIGNIFIE SOLAR CONSTANT EN ANGLAIS
Constante solaire
La constante solaire, une mesure de la densité de flux, est la quantité de rayonnement électromagnétique solaire entrant par unité de surface qui serait incidente sur un plan perpendiculaire aux rayons, à distance d'une unité astronomique. La constante solaire comprend tous les types de rayonnement solaire, pas seulement la lumière visible. Il est mesuré par satellite à environ 1.361 kilowatts par mètre carré au minimum solaire et environ 0.1% plus élevé au maximum solaire.
définition de solar constant dans le dictionnaire anglais
La définition de la constante solaire dans le dictionnaire est la vitesse à laquelle l'énergie solaire est reçue par unité de surface au sommet de l'atmosphère terrestre lorsque le soleil est à sa distance moyenne de la terre et que l'absorption atmosphérique a été corrigée. Sa valeur est de 1367 watts par mètre carré.
