  1. POLDIRAD and LINET observations during COPSMartin Hagen and Hartmut HöllerDLR Oberpfaffenhofen

  2. POLDIRAD and LINET • Installation of the DLR C-bandpolarimetric Doppler weather radar at Waltenheim-sur-Zornin Alsace. • PPI range 120 km • RHI towards Hornisgrinde • every 10 minutes • Enhancement of the operational lightning detection network by4 additional stations • Operations from June toAugust 2007. Achern POLDIRAD Hornisgr. Bischenberg AMF Meistratzheim 60 km 120 km Martin Hagen, COPS-Workshop, Toulouse, Dec. 2007

  3. POLDIRAD operation Quicklooks available athttp://www.pa.op.dlr.de/poldirad/cops and soon at WDCC Martin Hagen, COPS-Workshop, Toulouse, Dec. 2007

  12. DFG-PP Proposal within COPS bundle: Life Cycle of Precipitating Convective Cells Aim of the proposal: to study the life cycle of small precipitating convective cells from initiation to decay • initiation of cells in relation to orography, surface wind field related to orography, moisture field (radar, lidar, LINET, ... ) • live cycle of precipitation, variation of rain drop size distribution(polarimetric measurements) • enhancement or weakening in relation to orography • decay of cells, relation to orography, modification of rain drop size distribution • PhD student position open Martin Hagen, COPS-Workshop, Toulouse, Dec. 2007
