VALIDATION OF OZONE PROFILES RETRIEVED FROM SCIAMACHY LUNAR OCCULTATION MEASUREMENTS

Stratospheric number density profiles of ozone have been retrieved from lunar transmission spectra measured by Scanning Imaging Absorption Spectrometer for Atmospheric Chartography (SCIAMACHY), over the high Southern latitude (50 o S‐90 o S). The ozone profiles were retrieved from level-1 (calibrated) data using the spectral window of 520‐580nm. In order to assess the accuracy of the retrieved profiles, a comparison of the retrieved ozone profiles with ozone profiles inferred from POAM III, SAGE II and HALOE were carried out. The validation results show that the quality of SCIAMACHY ozone is within the accuracy better than 15% in the altitude range of 20‐40km.
