Abstract

Contemporary 3D dynamical atmosphere models include the mesosphere as an essential element of simulation framework. Though thousands of elementary chemical processes are included as well as horizontal and vertical transport processes the quality of models is unsatisfied from the radiowave propagation point of view. Below we consider additional physical mechanism to be included in simulation. It is of solar-terrestrial links nature, namely the background processes caused by X-rays, hard X-rays and gamma rays fluxes from Sun. The reanalysis of satellite data proves that within the period of high solar activity the aforementioned fluxes exceed the C- are level in a continuous manner. We present the satellite evidence and compare the present ionizing block with additional data from solar radiation.
