Tropospheric NO₂ trend over St. Petersburg (Russia) as measured from space

Faculty of Physics, St.Petersburg State University, St. Petersburg, Russia

Abstract

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 NO_x inventory studies.
