Regional Report on the current status of the exchange of weather radar data. RA VI Stuart Matthews, UK Met Office on behalf of EUMETNET OPERA April 24th 2013

GIE/EIG EUMETNET, Registered Number RPM Bruxelles Outline European collaboration (OPERA, BALTRAD, etc) OPERA Data information model (ODIM) OPERA Data Centre - Odyssey OPERA IV ECOMET Questions.

GIE/EIG EUMETNET, Registered Number RPM Bruxelles European exchange (a very brief history) Long history of exchanging radar products between nations and at regional level. –Nordic and Baltic (NORDRAD) –Central Europe –NW Europe (UK with IE, F, D, B, NL) Huge challenge of formats, product types, bandwidth, national objectives (hydrology, aviation, etc) Coordinated collaboration started with GORN and COST actions (late 90s) EUMETNET OPERA programme started in 1999

GIE/EIG EUMETNET, Registered Number RPM Bruxelles EUMETNET Established so National Weather Services in Europe can be efficient and effective. Provides a framework for European National Weather services to work together, share ideas and best practice and share costs of major infrastructure. Provide a collective voice when communicating with the European Union and other international bodies

GIE/EIG EUMETNET, Registered Number RPM Bruxelles EUMETNET – OPERA Operational Programme for the Exchange of weather RAdar information Started in 1999 and 4 th phase has just started with work agreed through to members and 3 cooperating members

GIE/EIG EUMETNET, Registered Number RPM Bruxelles EUMETNET – OPERA Operational Programme for the Exchange of weather RAdar information Opportunity for NMS to share information & experiences – 6 month Expert Team meetings, OPERA radar database (feed to WMO db) Sponsor work packages performed by various NMSs Promote standard radar production practices Help define common data format standards Organize and support Radar Data protection, e.g. wind farms and frequency Support the development and operations of a centralised processing capability to generate pan-European composites. The OPERA community has developed several software packages to enable exchange of radar data from different sources and manufacturers.

GIE/EIG EUMETNET, Registered Number RPM Bruxelles Other Region VI collaborations and exchange BALTRAD and BALTRAD+ –EU funded project –Advance weather radar network around Baltic Sea –Most BALTRAD members are also members of OPERA –Strong collaboration between OPERA and BALTRAD especially future Odyssey development Not all Region VI in OPERA or BALTRAD –Network ready radars in most ECMWF –US radar data

GIE/EIG EUMETNET, Registered Number RPM Bruxelles ODIM (OPERA Data Information Model) Big success of OPERA 3 Pioneered by SMHI (Sweden) and KNMI (the Netherlands) Adapted by OPERA and radar manufacturers. –ITT in Europe now often contain requirement for ODIM output Hierarchical approach Two encoded versions developed for OPERA: ODIM-HDF5 and ODMIN- BUFR

GIE/EIG EUMETNET, Registered Number RPM Bruxelles OPERA Data Centre - Odyssey 2009 – 2010 OPERA development of centralised capability to produce pan- European composites. Operational since January Joint operational responsibility between UKMO and Météo France Both centres processing the same data, creating same products using the same software/algorithms. Only one node disseminating products at any given time. High level of resilience with simple fail-over procedure. ~99.9% availability

GIE/EIG EUMETNET, Registered Number RPM Bruxelles OPERA Data Centre - Odyssey INPUT ~130 radars Polar (volumes or sent as individual sweeps) Reflectivity and recently radial winds too. Level II ODIM compliant BUFR or HDF5 Mostly use the internet rather than GTS/RMDCN OUTPUT 3 composites Max reflectivity, surface precipitation rate & hourly accumulation Uniform quality No-stitching BUFR and HDF5 2km 15 min updates, available DT+15minutes Whole European domain

GIE/EIG EUMETNET, Registered Number RPM Bruxelles OPERA Data Centre – 2011 to 2013 March 2011 (Dec 2012) April st pre-processing using BALTRAD’s toolbox Belgium, Croatia and Denmark added

GIE/EIG EUMETNET, Registered Number RPM Bruxelles OPERA 4, 2013 to 2017 New OPERA phase started in January 2013 Consortium of National Met Service led by FMI (Finland) and includes Sweden, France, UK and Croatia. Additional contribution from Poland, the Netherlands, Spain, Germany, Denmark, Belgium Producing a framework for collecting and generating quality index for incoming (generated at national level) and pre-processed (generated by Odyssey) data Redistribution of incoming data, with centrally generated QI, to NWP centres. Develop pre-processing modules with capability to produce products to at least same quality as national composites Develop 3D composites

GIE/EIG EUMETNET, Registered Number RPM Bruxelles ECOMET ECOMET. Economic Interest Group under Belgian Law Created in 1995 and has 25 members Created to: Preserve free and unrestricted exchange of meteorological information for operational functions To ensure wide availability of basic met data and products for commercial application Members make a wide range of radar products (Level III) available through a catalogue. Includes price. Developed policy for exchanging data between most European countries Data policy, including price, for Odyssey products almost agreed

GIE/EIG EUMETNET, Registered Number RPM Bruxelles Conclusions Most European exchange is organised by EUMETNET through its OPERA programme Regional networks are also well established (BALTRAD) and developing (Russia and her neighbours) Common data model (ODIM) has significantly simplified the exchange Now into 3 rd year of the operational European data hub generating pan European composite products OPERA 4 Framework for adding quality information to incoming volumes Development of pre-processing algorithms to improve quality Redistribution of raw data plus centrally produced quality index Commercially available Odyssey products
