Scanning lidar measurements of water vapor and temperature in the atmospheric boundary layer — •Florian Späth, Eva Hammann, Shravan Kumar Muppa, Simon Metzendorf, Andrea Riede, Andreas Behrendt, and Volker Wulfmeyer — University of Hohenheim, Institute of Physics and Meteorology, Garbenstr. 30, 70599 Stuttgart, Germany

The University of Hohenheim has developed and operates two unique high-resolution scanning lidar systems. One system uses the differential absorption lidar (DIAL) technique to determine atmospheric water vapor content. The other system is a rotational Raman lidar (RRL) with the focus of measuring temperature. These two systems were employed within the surface-atmosphere-boundary-layer exchange (SABLE) field campaign near Pforzheim (southwest Germany) in summer 2014. The goal of the campaign was to collect a new data set on the exchange processes of the surface and the vegetation with the boundary layer. For this, synchronized scanning measurements of the water vapor DIAL and the temperature RRL were performed for the first time. Additional vertical measurements were performed to analyze the entrainment processes between boundary layer and free troposphere.

The new set-ups of the two Hohenheim lidars and first results of lidar measurements during the SABLE campaign will be presented at the conference.
