Tropospheric columns for NO2 and H2O measured by AMAXDOAS over mid latitudes and tropics — •Klaus-Peter Heue¹, Marco Bruns², John Burrows², Ulrich Platt¹, Irene Pundt¹, Andreas Richter², Thomas Wagner¹, and Ping Wang² — ¹Institut fuer Umweltphysik, Universitaet Heidelberg, INF 229, 69120 Heidelberg — ²Institut fuer Umweltphysik, Universitaet Bremen, Postfach 330440, 28334 Bremen

The Airborne Multi AXis DOAS (AMAXDOAS) was successfully operated during a major SCIAMACHY-validation campaign in September 2002 reaching from the arctic to the tropics.

With four different viewing angles, two looking abowe and two below the aircraft, AMAXDOAS can distinguish between the tropospheric and the stratospheric columns for many trace gases e.g.: BrO, H2O, HCHO NO2, O3, SO2. One spectrum is taken every 30 sec; assuming a speed over ground of 220ml/h, this results in a horizontal resultion of 3.5 km.

The system was installed on the DLR-Falcon (D-CMET) together with the OLEX (lidar) and ASUR (microwave) instruments. We report on results of the southern track leading from Oberpfaffenhofen via Mallorca, Cameroon and Kenia to the Seychelles and back. Results for tropospheric NO2 and H2O will be presented.
