1. Definitions
Let's start with a few definitions, and clarify what we mean by :
absorption ;
distribution ;
extinction;
of the atmospheric propagation medium, as well as its transmission.
1.1 Atmospheric absorption
The absorption of radiation by the atmospheric medium involves interaction between the photons of radiation and the atoms or molecules of the medium. The result is a rise in temperature, the disappearance of the incident photon and a radiative emission proportional to that of the black body at the temperature reached. To assess the influence of the medium's absorption on the propagation of radiation, let's consider...
