For the period 1996ndash;2009, combined data set of tropospheric NO2 measurements by satellite instruments GOME, SCIAMACHY and OMI has been analyzed to derive possible trend over the city of St.nbsp;Petersburg in Russia. The time series of the monthly NO2 columns for these 14 years have been fitted with a linear function superposed on an annual seasonal cycle. Resulting trend estimate provides a linear growth of ~4% per year, which generally correlates with an independent assessments done by NOx inventory studies.
