Comparison of Tropospheric Ozone Columns as seen by SCIAMACHY using limb-nadir-matching with tropospheric Ozone Columns as seen from OMI/MLS — •Stefan Bötel, Annette Ladstätter-Weißenmayer, Felix Ebojie, Christian von Savigny, and John P.

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. Using OMI total columns and MLS stratospheric columns tropospheric ozone can be measured globally. Both instruments were launched in 2004 on Aura. A comparison of the global tropospheric ozone distribution from SCIAMACHY limb-nadir-matching with the distribution from OMI/MLS will be shown in study.
