Tropospheric Ozone from SCIAMACHY Limb-Nadir-Measurements — •Stefan Bötel, Felix Ebojie, Annette Ladstätter- Weißenmayer, Christian von Savigny, and John P. Burrows — Institute of Environmental Physics, University of Bremen, Bremen, Germany

SCIAMACHY (Scanning Imaging Absorption Spectrometer for Atmospheric ChartographY) launched in March 2002 measures sunlight, transmitted, reflected and scattered by the earth atmosphere or surface (240 nm - 2380 nm). SCIAMACHY measurements yield the amounts and distribution of O3, BrO, OClO, ClO, SO2, H2CO, NO2, CO, CO2, CH4, H2O, N2O, p, T, aerosol, radiation, cloud cover and cloud top height in limb as well as nadir mode. With it’s collocated limb and nadir measurements limb-nadir-matching can be used to determine tropospheric ozone columns from SCIAMACHY limb and nadir measurements. A comparison of tropospheric ozone columns determined from ozonesonde measurements with tropospheric ozone columns determined from SCIAMACHY using limb-nadir-matching in various latitude bands. The variability of using limb-nadir-matching to determine global distributions of tropospheric ozone will be investigated.
