Development of Diffusive-Photochemical of Model of Mars Atmosphere with Inclusion of Odd Nitrogen

Diffusive-photochemical model of Mars atmosphere composition of H-C-O-N is constructed in 0-250 km heights range. The model includes neutral atmosphere block and ionosphere. In the model there is interaction between neutral and ionized atmosphere that important for computation of H и H2. Preliminary results are obtained which fits the observational data.
