Tropospheric Ozone in the Tropics measured with GOME and compared with MATCH-MPIC-model O3-SHADOZ-Sondes-data — •Annette Ladstaetter-Weissenmayer1, John P. Burrows1, Rolf von Kuhlmann2, Mark Lawrence2, and Anke Schlemm1 — 1Institut fuer Umweltphysik Bremen — 2Max Planck Institut Mainz
The Global Ozone Monitoring Experiment (GOME) is the first European passive remote sensing instrument measuring the sunlight back scattered by the surface in nadir viewing mode in the spectral region 240-790 nm since its launch in April 1995 onboard ERS-2 in Kourou.
The main scientific objective of the GOME mission is to measure the global distribution of ozone (O3) and several other trace gases which play an important role in the chemistry of the Earth’s atmosphere, for example, NO2, BrO, OClO, HCHO and SO2.
In the tropics biomass burning is extensive every year and now considered to be one of the most significant sources of atmospheric pollution. During these burning events large amounts of aerosols and trace gases like nitrogen oxide (NOx), hydrocarbons, formaldehyde (HCHO) and carbon monoxide (CO) are emitted into the troposphere. In photochemical reactions tropospheric O3 is produced.
Tropospheric O3 based on GOME-data was analysed to observe an increasing of this trace gas during fire events and to compare then these results with the data of O3-SHADOZ-sondes and the MATCH-MPIC-model to validate the retrieval method.
