Abstract: | The tropospheric NO2 content over the Moscow region is analyzed on the basis of data of the satellite Ozone Monitoring Instrument (OMI) in the period 2004–2009. The spatial distributions of NO2 are presented, and some of their features are interpreted. The characteristics of the seasonal and weekly cycles of NO2 are described, as are its interannual and long-term variations. The relationship between the variabilities of the NO2 content and the aerological parameters is investigated on different time scales. The mutual influence of regional pollution and meteorological regimes is discussed. The seasonal and weekly NO2 cycles over Moscow are compared with those over the largest worldwide agglomerations. |
