Résumé:
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.
