Validation of SCIAMACHY Ozone Column Densities and Profiles Using Ground-Based FTIR and Millimeter Wave Measurements
Abstract
Ground-based FTIR and millimeter wave measurements of the Institute of Meteorology and Climate Research (IMK), Forschungszentrum Karlsruhe, and the Swedish Institute of Space Physics (IRF) are used for validation of SCIAMACHY ozone measurements. FTIR and millimeter wave measurements used for this study were routinely carried out between 2002 and 2004 at IRF at Kiruna, Sweden. In addition IMK carried out millimeter wave measurements on Mount Zugspitze in the Alps in 2003. SCIAMACHY level 2 NRT-products of 2002 are only validated by FTIR data since millimeter wave observations started in late 2002 when SCIAMACHY data were unavailable. For the years 2003 and early 2004 total ozone column abundances retrieved with the TOSOMI algorithm of the Royal Netherlands Meteorological Institute (Koninklijk Nederlands Meteorologisch Instituut, KNMI) are validated by the FTIR and microwave measurements. Finally, ozone limb profiles between July and November 2002 taken from the current SCIA Level 2 Off-Line masterset are validated by the FTIR measurements at Kiruna
