European Weather Radar Network: OPERA Overview

Learn about OPERA, the European Weather Radar Network, aiming to harmonize radar data exchange and support operational weather applications through a Data Hub. OPERA evaluates new radar technology and bands to enhance operational services. The network consists of 30 members coordinating over 190 radars. Working groups focus on radar technology, data exchange software, and operational projects. Explore OPERA initiatives for weather radar wind profiles, GTS headers, and the Pilot Data Hub. Stay updated on OPERA's collaborations with WMO, EUMETNET, and more on the official website.

  3. OPERA’s Mission • Is to “harmonize and improvethe operational exchange of weather radar information between National Meteorological Services” • “To support European applications of weather radar data through the establishment of a Data Hub function where harmonised products … are generated and managed.” • “To investigate and evaluate new radar technology and its relevance to operational requirements for present and future radar systems and bands.” • OPERA stands for OperationalProgramme on Exchange of weather RAdar information • Oriented towards operations • 30 members, KNMI is the coordinating member

  4. OPERA Network • More than 190 radars • Mostly C-band ●, some S-band ● and X-band ● • About 160 Doppler radars • Some 30 polarimetric radars, all Doppler radars • Polarimetric radars are becoming operational standard

  5. Organization • OPERA group meets twice a year • Typically 25-40 delegates from 20 countries • Plenary session and working groups • WG1 (Delobbe): Radar Technology and Algorithms • WG2 (Urban): Formats, Software, Data Hub

  6. Projects of WG1 • Working Group 1 is concerned with: • Weather Radars in Europe (Database on website) • Quality information for radars and radar data • Evaluation of new technologies (Polarimetric radars, X-band) • Site and frequency protection (Link with EUMETFREQ) • Harmonized production practices

  7. Projects of WG2 • Working Group 2 is concerned with: • ODIM (OPERA data information model) • Data exchange software development (BUFR and HDF5) • BUFR software and table maintenance (Software available on website) • Pilot Data Hub operations (Developed during OPERA-2) • OPERA Data Center: specification, development, and operation

  8. OPERA and E-WINPROF • Weather radar wind profiles • Increase of availability, ~100 sites • Harmonization of GTS headers, format, and content • Improvements on the quality

  9. Frequency protection • Close co-operation with EUMETFREQ • RLAN issues • WLAN on air planes • Spurious transmission • etc

  10. Pilot Data Hub

  11. OPERA Data Center • Under development, to start operation 2011 • Collects single site 3D volume data • Produces 2D composites • Maximum reflectivity • Rainfall intensity and accumulation

  12. OPERA and WMO • OPERA and OPAG ET for Upper Air work both with • Radar database • Data formats • Harmonization • New technology • Wind turbines • RLAN issues • Quality information • Possibility for joint work and co-operation
