Airborne differential absorption and high spectral resolution lidar measurements for aerosol and cirrus cloud studies — •Silke Groß, Martin Wirth, Andreas Schäfler, and Andreas Fix — Deutsches Zentrum für Luft- und Raumfahrt, Insitut für Physik der Atmosphäre, Oberpfaffenhofen

Airborne lidar measurements were performed with the WALES system of the German Aerospace Center (DLR), Oberpfaffenhofen, which comprises high spectral resolution lidar (HSRL) and water vapour differential absorption lidar (DIAL) capability to measure the 2-dimensional distribution of aerosols and humidity along the flight track. The system was operated onboard the German long range and high altitude research aircraft HALO. During three flight campaigns, the Technomission in October/November 2010, the NARVAL mission in December 2013 and January 2014, and the ML-Cirrus campaign in March/April 2014, more than 200 flight hours were performed over Central Europe, the Tropical North Atlantic and the Extra-tropical North Atlantic region.

In our presentation we will give a general overview of the campaigns and the WALES measurements, and we will show first results of the lidar measurements with focus on cirrus cloud structure and humidity distribution within and outside the cirrus cloud.
