  1. Quality Management of a European Wind Profiler Network (CWINDE) Tim Oakley TECO-05 Bucharest, 4th-7th May

  2. Introduction • EUMETNET & WINPROF • CWINDE Hub Status • Products & Quality Monitoring • Challenges for the Future

  3. What is EUMETNET? • EUMETNET is a network grouping 18 National Met. Services. • Provides a framework to organise co-operative programmes. • Members aim to develop their collective capabilities to serve environment management & climate monitoring. • Bring to all European users the best available quality of meteorological information. • Make more efficient the management of their collective resources

  4. EUCOS E-ASAP AWS SWS OBS-INFO Protection of Radio Frequency E-AMDAR SURFMAR PWS OPERA RADIOSONDE WINPROF Observations Programmes

  5. WINPROF main objectives • 2 year EUMETNET Project - started 1/7/2002 • Harmonise and improve the existing exchange of all wind profiler (from National Met Services and Universities) and Weather radar profiler data in Europe. • Run and further develop a network hub for data processing and quality evaluation. • Integrate new wind profiler systems.

  6. WINPROF main objectives • Establish appropriate quality control procedures. • Define general quality standards and user requirement for operational use. • Work on improved processing algorithms to improve data quality/availability. • Provide expert support to members for wind profiler installations.

  7. Current/Future Wind Profiler sites Red indicates that data is expected in the near future.

  8. Current/Future - Weather Radar Wind Sites Red indicates that data is expected in the near future.

  9. HOW THE DATA IS PROCESSED

  10. Data Frequency • VIA GTS(BUFR) - 3500 MESSAGES/DAY (32 SITES) • VIA GTS(ASCII) - 600 MESSAGES/DAY (13 SITES) • VIA FTP-OUT(ASCII) – 1200 MESSAGES/DAY (4 SITES) • VIA FTP-IN (BALTRAD) - 1750 MESSAGES/DAY (19 SITES) • VIA FTP-IN (ASCII) - 250 MESSAGES/DAY (6 SITES) • VIA FTP-IN (BUFR) - 24 MESSAGES/DAY (1 SITE) • VIA NETLINK (BUFR) - 50 MESSAGES/DAY (2 SITES) • VIA E-MAIL (ASCII) - 48 MESSAGES/DAY (1 SITE) – to be suspended soon. • TOTAL OF ~7,500 MESSAGES/DAY (~77 SITES)

  11. Wind profiler real-time data averages

  12. Weather radar winds real-time data averages

  13. Hub Requirements (Hub managed by UK Met Office) • Provision of wind data for NWP • Provision of displays for Forecasting & Monitoring • Feedback of Quality Monitoring to Operators • Maintain expertise in communication & coding (BUFR) • Maintain a data archive • Develop new products

  14. Wind Barbs Example – South Uist

  15. SNR Example – South Uist

  16. Wind Profiler v Weather Radar (VAD)

  17. Plan view Plots Now updated every 3hrs. No longer relies on model fields. Faster method of data extraction.

  18. Monitoring Statistics against NWP models. • Monthly monitoring against UK NWP. • Monthly statistics from Meteo France. • Offline ‘network’ statistics available from ECMWF. • Future – Statistics from DWD (Germany)

  19. UK Monthly Model Statistics

  23. ECMWF ( Aug04) – Wind Direction (All systems)

  24. ECMWF ( Aug04) – Wind Direction (Used systems)

  25. ECMWF ( Aug04) – Wind Speed (All systems)

  26. ECMWF ( Aug04) – Wind Speed (Used systems)

  27. ECMWF Aug04 - Networks Europe Japan USA

  28. CWINDE WEB SITE Hosted by UK Met Office. UK Model Assimilation Status added. New web address – www.metoffice.gov.uk

  29. Challenges for the future. • Maintain a network of diverse systems operated by different organisations. • WINPROF II (starts 01/05/05 – UK Programme manager). • By 2007 by ready to incorporate wind profilers as part of EUCOS. ( European Observing Systems) • Work to increase the number of wind profiler systems acceptable for data assimilation. • Develop the use of other products and high resolution data. • Technical support to the Galileo & 1290MHz wind profiler issue. • Possible expansion of network hub to include other systems. (Weather radar products, GPS Water Vapour)
