Retrieval of O2 A-band volume emission rates in the mesosphere and lower thermosphere from SCIAMACHY MLT limb scans — •Amirmahdi Zarboo¹, Stefan Bender¹, Miriam Sinnhuber¹, and John Burrows² — ¹Karlsruhe Institute of Technology, Karlsruhe, Germany — ²University of Bremen, Bremen, Germany

We use the visible and near infrared spectra in the range 595-811 nm from the SCanning Imaging Absorption spectroMeter for Atmospheric Chartography (SCIAMACHY) on-board the European Space Agency's ENVISAT satellite to retrieve O2 volume emission rates (VERs) from atmospheric emissions in the A-band (759-767 nm) in the mesosphere-lower thermosphere (MLT, 50-150 km) region.

Using single profile retrieval, we retrieve profiles on the measurement grid in the altitude range from 53 to 148 km. We present details of the retrieval algorithm and the latitudinal / altitude variation of the global O2 VER as first results. The whole SCIAMACHY MLT dataset from 08/2007 to 04/2012 will be retrieved. Further it is planned to use the O2 VER also from the nominal limb mode of SCIAMACHY to calculate the temperatures in the MLT region, acquire its time series, and investigate MLT region responses to external forcings.
