DWD framework concept on future development of the oberving system (1) Initial start: WMO RRR process, WMO Vision 2025, EGOS-IP DWD Strategy 2014-2020, detailed concepts for weather, climate with special requirements and on the observing system at national level for 2025 Integrated forecast system from nowcasting to long range forecast Ensemble Data Assimilation 15 min update cycle for observations and/or near real time using streaming techniques Additional surface based remote sensing observation of the boundary layer 3D scans from Weather Radar with 5 min update cycle, polarimetric information PBPV – 03/2013

DWD framework concept on future development of the oberving system (2) Nowcasting and warning service More use of data from partner networks (wind, temperature, humidity, snow) Crowd sourcing information (lightning, thunderstorm, hail heavy precipitation) Video camera systems Aeronautical Meteorology Improved services in the framework of Single European Sky, SES Automation of METAR Climate applications Use of Weather Radar data for climate Combination of satellite and ground based information ( i.e. radiation, snow cover) Special observations for urban applications PBPV – 03/2013
