Satellite monitoring of the NO2 content in the ambient air of populated areas is concurrently a specific and an innovative method of environmental monitoring. It provides information on NO2 concentrations in locations where ground-based observation systems are not available. In particular, this is typical for three cities in the north of the Moscow region being Taldom, Dmitrov and Sergiyev Posad. Analysis of satellite data on the NO2 content in the troposphere above the indicated territories showed that the average values of Taldom were 3.4E+15 molec/cm2, Dmitrov – 4.0E+15 molec/cm2, Sergiyev Posad – 4.2E+15 molec/cm2 for the years 2005-2020. For comparison, these indicators were lower than the level of Moscow on average by more than two times. The main source of NO2 for the study areas is, in general, Moscow.
