Calcul du rayonnement diffus en utilisant les paramètres de la théorie de Mie.

Abstract

In this work, several theoretical and numerical tools have been used to quantify the radiation scattered by atmospheric aerosols which are illuminated by a monochromatic radiation. Using certain assumptions, we applied the Mie theory to characterize at the first time the optical properties such the extinction efficiency, scattering efficiency, absorption efficiency and the simple Aledo then the intensities distribution in all space such the phase function, forward scattering, backscattering and the light scattering at any angles between 0°≤θ ≤180° . Then we expanded our calculation model for a set of aerosols having a single refractive index and a wide range of diameters. Using the methods of numerical integration and functions of size distribution, we estimated the radiation scattered by them within the framework of the simple and elastic scattering.
