One-dimensional numerical model with a size distribution of aerosol particles in Martian atmosphere is developed. The diurnal cycle of condensational processes is obtained on the basis of temperature profiles from 3D GCM. An effective radius of ice particles varies from 1 to 2 μm at lower layers of the cloud and it varies within 0.2-0.3 μm above 50 km. These results are consistent with data from SPICAM experiment on Mars-Express. Dependence of condensational process and macroscopic parameters on microphysical properties of aerosol particles is analyzed. One dimension model with modified spatial dynamics is also presented, basing on the approximation of fractional diffusion.
Keywords: microphysical processes, fractional diffusion, numerical simulation
