Stuart Matthews, UK Met Office on behalf of EUMETNET OPERA
April 24th 2013
European collaboration (OPERA, BALTRAD, etc)
OPERA Data information model (ODIM)
OPERA Data Centre - Odyssey
Long history of exchanging radar products between nations and at regional level.
Nordic and Baltic (NORDRAD)
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
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
Started in 1999 and 4th phase has just started with work agreed through to 2017
27 members and 3 cooperating members
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.
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
US radar data
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
Two encoded versions developed for OPERA: ODIM-HDF5 and ODMIN-BUFR
2009 – 2010 OPERA development of centralised capability to produce pan-European composites.
Operational since January 2011. 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
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
Operationally receiving data from 20 countries
Various temporal resolutions. 7 x 15min, 5 x 10min and 8 x 5min
Most send volumes but some single elevation 16 x Volumes and 4 x individual scans but these account for nearly 60 radars
As of February 2013, 5 countries send wind data in the volumes
Most countries use HDF5. 2x BUFR (over 40 radars), 17 x HDF5 and one country uses both
1Countries using RMDCN to send data
1st pre-processing using BALTRAD’s toolbox
Belgium, Croatia and Denmark added
