For the period 1996–2009, 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. 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.
