Page 2© Crown copyright 2004 Introduction  EUMETNET & WINPROF  CWINDE Hub Status  Products & Quality Monitoring  Challenges for the Future

Page 3© Crown copyright 2004 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

Page 4© Crown copyright 2004 Observations Programmes  EUCOS  E-ASAP  AWS  SWS  OBS-INFO  Protection of Radio Frequency  E-AMDAR  SURFMAR  PWS  OPERA  RADIOSONDE  WINPROF

Page 5© Crown copyright 2004 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.

Page 6© Crown copyright 2004 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.

Page 7© Crown copyright 2004 Current/Future Wind Profiler sites Red indicates that data is expected in the near future.

Page 8© Crown copyright 2004 Current/Future - Weather Radar Wind Sites Red indicates that data is expected in the near future.

Page 9© Crown copyright 2004 HOW THE DATA IS PROCESSED

Page 10© Crown copyright 2004 Data Frequency  VIA GTS(BUFR) MESSAGES/DAY (32 SITES)  VIA GTS(ASCII) MESSAGES/DAY (13 SITES)  VIA FTP-OUT(ASCII) – 1200 MESSAGES/DAY (4 SITES)  VIA FTP-IN (BALTRAD) MESSAGES/DAY (19 SITES)  VIA FTP-IN (ASCII) MESSAGES/DAY (6 SITES)  VIA FTP-IN (BUFR) - 24 MESSAGES/DAY (1 SITE)  VIA NETLINK (BUFR) - 50 MESSAGES/DAY (2 SITES)  VIA (ASCII) - 48 MESSAGES/DAY (1 SITE) – to be suspended soon.  TOTAL OF ~7,500 MESSAGES/DAY (~77 SITES)

Page 12© Crown copyright 2004 Weather radar winds real-time data averages

Page 13© Crown copyright 2004 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

Page 29© Crown copyright 2004 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.
