Kick-Off-Treffen PQP 23./24. Oktober Bonn gather as many data about the atmospheric state as possible within an area covering Germany and it neighboring states. to provide information of all kinds of precipitation types to identify systematic model deficits to select case studies for specific problems to relate the COPS results to a broader perspective (longer time series and larger spatial domain) GOP Organization and Performance The General Observation Period January to December 2007 encompasses COPS in time and space

Kick-Off-Treffen PQP 23./24. Oktober Bonn WP-GOP-9 GOP Management Optimized exploitation of existing instrumentation; (inter-)national contacts Provison of data suitable for statistical model evaluation/analysis - high quality - continuous observations or well defined temporal sampling - error characteristics (instrument limitations) - consideration of spatial and temporal scales quicklooks and online evaluation of LM(K) forecasts quality assessment and production of value-added products High spatial and temporal resolution satellite data of multiple parameters to study - diurnal cycle - tracks of convective systems - sub-grid statistics... Near-real time availability for close interaction with PQP projects

Kick-Off-Treffen PQP 23./24. Oktober Bonn Satellites MSG: - cloud mask - cloud top pressure (+temperature?), - optical depth - IR brightness temperature MODIS: - cloud mask - cloud optical thickness τ - liquid water path LWP - effective radius r eff - geometric cloud thickness H - IWV - aerosol?
