  1. EUCOS Short presentation of the EUCOS/PREVIEW Data Targeting System (DTS) Fourth WMO Workshop on the Impact of Various Observing Systems on Numerical Weather Prediction 19-21 May 2008, WMO, Geneva, Switzerland Stefan Klink (EUCOS), Stewart Turner (Met Office), David Richardson, Cristina Prates, Cihan Sahin (ECMWF) www.free-stockphotos.com

  2. Data Targeting System • 50% funded by Eurorisk PREVIEW • 50% funded by EUCOS • Aim is to deliver additional meteorological observations over key sensitive regions to aid: • Prediction and early warning of high impact weather events over Europe • Reduction of forecast uncertainty • Support crisis management over regions impacted by severe events by providing access to targeted Met observations • Met Office lead, partnering with ECMWF. • Pre-operational trial began in February 2008 (restricted users) • Full access to all interested users began in March 2008 • A website for the system exists at:http://www.ecmwf.int/research/EU_projects/PREVIEW/DTS/index.html 4th WMO OSE/OSSE Workshop 19-21 May 2008, WMO, Geneva, Switzerland

  7. Statistics 4th February to 22nd April 2008 (inclusive) • Cases suggested by UKMO, Meteo-France, ECMWF and DWD • Total number of cases proposed: 112 • Total number of cases accepted: 99 • Additional 73 cases from the IPY-THORPEX experiment (automatically accepted) • SACs are performed for all accepted cases • Extra observations requested from 42 cases • 201 observations requested (including AMDAR) • 155 observations requested (excluding AMDAR) • 110 extra observations deployed (excluding AMDAR) 4th WMO OSE/OSSE Workshop 19-21 May 2008, WMO, Geneva, Switzerland

  8. Summary • The DTS is progressing according to schedule • A prototype trial demonstrated that: • Very significant efficiencies have been achieved since the 2003 A-TReC activity • The DTS is a very straightforward and user-friendly tool • Good level of participation • 18 Participating European Met. Services • User base OK but could be larger • 9 Users volunteered • 6 registered (UK, Germany, France, Finland, Sweden, Netherlands) • 3 have suggested cases (UK, Germany, France) 4th WMO OSE/OSSE Workshop 19-21 May 2008, WMO, Geneva, Switzerland
