Validation of the Limb-Nadir-Matching Method for the Determination of Tropospheric Ozone in the Subtropics and Middle Latitudes — •Stefan Bötel, Annette Ladstätter-Weißenmayer, Christian von Savigny, and John P. Burrows — Universität 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. In this study data for the time period of 2003-2008 is used for the determination of tropospheric O3. Comparisons of the results of the retrieval of tropospheric O3 using satellite based data and sonde profiles will be shown for latitudes in the subtropics and middle latitudes. The main focus will be validation of the Limb-Nadir-Matching method for tropospheric O3 retrieval using sonde date.
