VALIDATION OF SCIAMACHY OZONE COLUMN DENSITIES AND PROFILESUSING GROUND-BASED FTIR AND MILLIMETER WAVE MEASUREMENTS

摘要

Ground-based FTIR and millimeter wave measurementsrnof the Institute of Meteorology and Climate Researchrn(IMK), Forschungszentrum Karlsruhe, and the SwedishrnInstitute of Space Physics (IRF) are used for validationrnof SCIAMACHY ozone measurements. FTIR and millimeterrnwave measurements used for this study werernroutinely carried out between 2002 and 2004 at IRF atrnKiruna, Sweden. In addition IMK carried out millimeterrnwave measurements on Mount Zugspitze in the Alps inrn2003.rnSCIAMACHY level 2 NRT-products of 2002 are onlyrnvalidated by FTIR data since millimeter wave observationsrnstarted in late 2002 when SCIAMACHY data werernunavailable. For the years 2003 and early 2004 totalrnozone column abundances retrieved with the TOSOMIrnalgorithm of the Royal Netherlands MeteorologicalrnInstitute (Koninklijk Nederlands Meteorologisch Instituut,rnKNMI) are validated by the FTIR and microwavernmeasurements. Finally, ozone limb profiles betweenrnJuly and November 2002 taken from the current SCIArnLevel 2 Off-Line masterset are validated by the FTIRrnmeasurements at Kiruna.
