Biomass burning affects strongly the atmospheric conditions in the tropics. That means trace gases like hydrocarbons, carbon monoxide (CO) and nitrogen oxides (NOx = NO + NO₂) are emitted in high concentrations. Consequently in photochemical reactions tropospheric ozone (O₃) is produced.
In this respect, remote sensing data from the ERS-2 ATSR-2 (Along Track Scanning Radiometer) provide an opportunity to study the impact of biomass fires on Tropical Tropospheric Ozone (TTO). During pollution events caused by biomass buring the combination of the ATSR data, the comparison of the TTO (Tropical Tropospheric Ozone) for all SHADOZ (Southern Hemisphere Additional Ozonesondes) stations with the tropospheric ozone columns based on GOME (Global Ozone Monitoring Experiment) measurements and in addition the calculation of the trajectories give information about transport processes influenced by their local meteorology, e.g. by long-range transport, African fires emissions contributes to South American air pollution.
