Validation of TROPOMI Satellite Measurements of the NO2 Content in the Troposphere and Stratosphere with Ground-Based Measurements at the Zvenigorod Scientific Station of A.M. Obukhov Institute of Atmospheric Physics, Russian Academy of Sciences

Results of measurements of the tropospheric and stratospheric NO₂ columns with the TROPOMI (Tropospheric Monitoring Instrument) aboard the Copernicus Sentinel-5P satellite in 2018–2020 are compared with the results of ground-based measurements at the Zvenigorod Scientific Station (ZSS) of A.M. Obukhov Institute of Atmospheric Physics, Russian Academy of Sciences. The correspondence between the satellite and ground-based measurements is characterized by the difference between them, the linear correlation coefficients, and the regression coefficients. The dependences of these parameters on the season, cloud conditions, and the height of the atmospheric boundary layer are derived. [ABSTRACT FROM AUTHOR]
