Stratospheric trace gas measurements by the Airborne Submillimeter Radiometer ASUR during SCIA-VALUE 2002 (validation and utilisation of ENVISAT and SCIAMACHY data products)

Numerous measurements of the stratospheric trace gases ozone, HCl, HNO/sub 3/, and N/sub 2/O were performed by the Airborne Submillimeter Radiometer ASUR in September 2002. ASUR was deployed on board the German research aircraft FALCON during the SCIA-VALUE 2002 campaign. A latitudinal range between 80/spl deg/N and 5/spl deg/S was covered, enabling ASUR to perform extensive measurements in the tropics for the first time. First retrievals of stratospheric trace gas profiles are presented and their dependence on latitude is studied.
