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

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.

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.

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)
