A modern three-dimensional chemistry transport model is adopted for computation of air pollution with photo-oxidants in the Moscow megalopolis and in the several neighboring regions. Along the vertical, the model covers the entire troposphere and has a two-scale horizontal structure, when the resolution of the “inserted” domain is about 13 km. The model computation results are compared with the satellite tropospheric nitrogen dioxide measurements and ground-based measurements of the surface ozone concentration. The analysis results of one of the episodes of enhanced ozone content is considered as an example of a possible use of the model considered as a diagnostic tool for studying issues connected with the air pollution in the region under consideration.
