Examples of BIRA-IASB implications in air quality studies
Satellite data and modeling estimates of air pollutant emissions
BIRA-IASB has also developed advanced methods to make the most of the satellite observations of the chemical compounds involved in atmospheric air pollution.
In particular, tropospheric chemical models (i.e., mathematical/numerical representations of the troposphere composition) have been created to determine the influence of the natural and anthropogenic emissions (i.e., produced by human activities) of key pollutants, such as nitrogen oxides (NOx) and hydrocarbons.
These compounds are the main cause of photochemical smog; however, their emissions are still poorly known. Therefore, we used our global model of tropospheric chemistry in combination with satellite measurements in order to provide better emission estimates.
