  1. The New Meteorological Observation Network in the Netherlands; Status and Operational Experience Wiel Wauben and Dennis Hart Royal Netherlands Meteorological Institute (KNMI) TECO 2002: HIM-project, reason, concept, automation TECO 2005: Current status and experience

  2. HIM-project • 90’s First investigations, preparations • 1999 EU tender procedure • Jan 2000 Contract with Almos Systems • 2000 Requirements, Specifications and Design • 2001/2002 Building, HMI prototyping, testing Implementation of the 2 largest stations by Almos • 2002 Implementation other stations by KNMI parallel to old system • 21 Nov 2002 Synoptic part operational • 28 Jan 2003 Airports operational (data format ATC changed)

  3. Dutch Surface Observation Network • 21 automated stations (PTUWRQ  Visibility, Weather, Cloud  research tower Cabauw) • 5 civil airports (regional  5RWY Schiphol) • 2 Navy airbases • ~70 Ministry of Waterworks and Transport met-hydro stations(inland waters, coastal region, North Sea) • Lightning detection system (Safir Vaisala) • Precipitation radar (Gematronic) • MetClock (Cloud info from METEOSAT) • Many changes to sensor configuration and some stations • 9 Royal Netherlands Air Force airbases added 2004/2005

  4. 2005/2006 9 platforms MetNetAutomated Stationsand Airport Systems KNMI Navy Air Force

  5. MetNet Data Flow

  6. Visualisation/configuration/maintenance/report-entry within MetNet using Almos client systems. Maintenance staff and observers/forecasters. • 10-minute data of entire MetNet provided to internal and external users. • Visualised by KNMI applications in time series and geographically incl. alarms and presented on intranet. • Local presentation of 12-second airport data for ATC, Fire brigade, SAR... Data Usage/Visualisation

  7. Sensor map Schiphol airport

  8. System overview central site

  9. 12-second local presentation

  10. 10-minute intranet presentation

  11. 10-minute AVW tools

  12. Airport system Schiphol60 SIAMs; 66 sub-stations (physically 23xZM, pseudo, other airports)12 ‘Runways’; 2 take-off + 2 landing, Reg. QNH & TLrunway dep. sensors; backup sensors; cross/tail winds etc.12 sec. updates (1300 variables out of 2100) • Central system De Bilt21 AWSs; 7+9 airports; 27 DNZ; 20 ZEGE; 26 MSWtotal of 350 (sub)stations2500 1-min variables; 4900 10-min; 9600 total; 7 days • Configuration changes (distributed centrally) > 100. MetNet Key Numbers

  13. Availability

  14. MetNet Evaluation and Future • Project finished on time with required functionality and stable.Cooperation Almos and KNMI resulted is a good product. • Maintenance had difficult and busy start.MetNet very dynamic: 5th RWY Schiphol, renumbering RWYs, many sensor and some station changes, 9 airbases). • New functionality: FLITS, Auto METAR, Auto Trend, security issues, maintenance tools, OS upgrade. • Upcoming changes: ISDN  GRPS,AVW-RNLAF, FTP-XML format platforms, BUFR, bugs/wishes... • Tools for 10-minute data visualisation and experience in usage.
