Paper Abstract

The GOME was launched on the European Space Agency's ERS-2 satellite on April 20, 1995. GOME measures the Earth's atmosphere in the nadir geometry, using four spectrometers that cover the UV and visible at moderate resolution, employing silicon diode array detectors. GOME takes some 30,000 spectra per day, obtaining full global coverage at 40 X 320 km2 resolution in three days. It provides measurements of ozone, NO2, SO2, H2CO, H2O, BrO, ClO, and OClO. We directly fit GOME radiance spectra using nonlinear least-squares analysis to obtain column amounts of several trace species, including ClO, BrO, SO2, and H2CO. The use of recent improvements in the underlying physical and spectroscopy permits the fitting of radiances to very high precision, approaching 2 X 10-4 in favorable case, for standard 1.5s integration time GOME measurements. Examples of the fitting of BrO and SO2 are presented here.
