One-Dimensional Model of Vertical Transport of Chemical Components in the Mars Atmosphere up to the Lower Thermosphere

This study is devoted to the analysis of transport of chemical components of the Mars atmosphere. We investigate the turbulent diffusion of chemical components of the Mars atmosphere. To solve this problem in the approximation of diffusion of the minor component, we composed the continuity equation and the corresponding difference scheme. We formulated the boundary conditions in accordance with the available experimental and theoretical data and obtained the required temperature and pressure profiles. For simulation, we chose two models of turbulent diffusion, which were used in subsequent calculations. The simulation was performed using the modified Newton method. The models showed significant differences in the distribution of minor components of the atmosphere, in particular, hydrogen-containing molecules, which indicates the importance of choosing a model for describing turbulent diffusion when constructing a one-dimensional photochemical model of the atmosphere.
