Atmospheric turbulence models for vertical optical communication

This work is focused on the selection of appropriate turbulent models for determining the vertical profile of the refractive index structure parameter for communication between the Ground Optical Station and the optical terminal at a high altitude above the Earth’s surface. We have determined the procedure for determining the length of the optical path for the vertical and slant directions. We have chosen Hufnagel’s turbulent model from the described vertical turbulent models to demonstrate the analysis of the vertical communication link. We proposed the parameter R turbutence , which represents how the path of the slant direction of communication through the turbulent layers will be extended compared to the vertical direction.
