Projects
ROMIC
In ROMIC (Role of the Middle Atmosphere in Climate) we investigate the life cycle of internal gravity waves.
PANDOWAE
In PANDOWAE (Predictability ANd Dynamics Of Weather Systems in the Atlantic-European Sector) we quantify the role of diabatic processes for forecast errors associated with mid-latitude weather systems. The collaboration with Heini Wernli is a combined observational, diagnostic and modelling approach.

T-REX
The Terrain-Induced Rotor Experiment (T-REX) took place in March/April 2006 in the Owens Valley, Sierra Nevada, California. The DLR Institut für Physik der Atmosphäre operated a coherent 2 µm Doppler lidar from Lockheed Martin Coherent Technologies to investigate the dynamics of mountain waves and rotors.
