  1. Recent developments at DMI Jacob Brock jbb@dmi.dk Weather, climate and sea

  2. Recent developments at DMI • An administrative change • NinJo: Operational introduction and continued development • A new supercomputer • Road Weather Information System • Graphical Production System

  3. An administrative change

  4. NinJo

  5. NinJo • Deployed operationally Dec 2006 • 4 data types: • Observations • Model data (HIRLAM) • Radar • Satellite • In parallel with old system

  6. NinJo • Lightning data, more models added • Experiences (subjective) • Younger users more likely to use NinJo • Good super users gives better acceptance • Don’t try to limit the users

  8. New supercomputer

  9. Supercomputer • Replacing the current NEC SX6 with a Cray in 4 steps: • An XT4 as an ”early migration system” in parallel with the NEC has been installed • The XT4 takes over all applications and the NEC is closed down (scheduled 16 July) • The NEC is disassembled and a Cray XT5 put in instead • The XT5 to be turned on late october and take over all applications before the end of the year

  10. Cray XT: Homogenous Architecture, scalable nodes

  11. Supercomputer • Software • - loginnodes have full SuSE Enterprise Linux • - compute nodes have Compute Node Linux (speciel kernel and version of SuSE) • - third party compilers, amongst others PGI, PathScale, Gnu GCC • Cost • - Cray XT4/5, 6 million € • - refurbishing of machine hall ~450.000 € • - other costs ~65.000 €

  12. XT4 ”Odin”

  13. Road Weather Information System

  14. Road Weather Information System • Once it was MFC C++ • Then it became JavaScript • But that was too slow so… • Now reimplemented in pure Java, using Java WebStart for updgrading

  15. The Challenge: Provide complex meteorological information in a non-complex format The Construction Syndicate: Road People Weather People IT People The Users: Basicly everyone with interests in slippery road conditions…

  16. User spectre : Owner of truck or shovel, may have drivers license Engineer, who is a full time computer- and weathernerd • The Users: • Basicly everyone with interests in slippery road conditions : • Road authorities, State, Region, Community, City…. • Entrepreneurs • Airports • Harbours • Hospitals • Other authorities • …

  17. Local map Current condition Forecast status 5 hours

  18. Longforecast ~330 stations !

  19. Area forecast Comments from meteorologist

  20. Radar images (Precipitation) Rain Mix Snow FRZ precip

  21. Web-cams

  22. The system is continously improved • Feed-back from users • Performance continuously verified • Day seminar every year • Next season: Exchanging data with Schleswig – Holstein (Northern Germany)

  23. Graphical Production System

  24. Graphical Production System • So far based on a locally developed program • Written in MFC C++, no further development • Can only generate pixel-based images • Does not scale very well • New product = new extraction + new graphics + new dissemination

  25. Graphical Production System • Requirements for new system • Based on common standards • Deliver both pixel and vector graphics • Illustrator CS-series chosen • Be scalable • Common products for many customers

  26. Graphical Production System Database Production application Data + prod. Req. Illustrator CS Product Post processing

  27. Graphical production
