2. Institut für Physik der Atmosphäre Folie 2 > Vortrag > Autor Goals and Status Identify sensitive regions, i.e. optimal locations for supplementary observations for convective events in two European regions 1. COPS (guidance for targetted observation missions) 2. Mediterranean (preparation for future HYMEX campaign) Status of preliminary work Four case studies from 2006, showing typical weather patterns For first case June 27 2006, four sets of preliminary results received, Initial impression: variety of methods (good), variety of results (bad)
