Satellite Monitoring of Nitrogen Oxide Emissions
The efficient control of air pollutant emissions into the atmosphere is important for sustainable development. Remarkable recent progress in satellite measurements of the composition of the troposphere has opened new prospects for monitoring of air pollution and emissions of pollutants. This paper presents examples of using satellite measurements of atmospheric composition for estimation of long-term changes of emissions in nitrogen oxides which are important air pollutants playing a major role in photochemical smog formation. The estimations are based on the use of inverse modeling methods enabling combination of the data for tropospheric NO2 column amounts derived from the long-term (1996–2008) GOME and SCIAMACHY satellite measurements with simulations performed by the CHIMERE chemistry transport model.
