Questions.

european exchange a very brief history
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

eumetnet
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

eumetnet opera o perational p rogramme for the e xchange of weather ra dar information
EUMETNET – OPERAOperational Programme for the Exchange of weather RAdar information

Started in 1999 and 4th phase has just started with work agreed through to 2017

27 members and 3 cooperating members

EUMETNET – OPERAOperational 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.

other region vi collaborations and exchange
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

odim opera data information model
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

opera data centre odyssey
OPERA Data Centre - Odyssey

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

opera data centre odyssey1
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
country status
Country Status

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

opera 4 2013 to 2017
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
ecomet
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
conclusions
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 3rd 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
