6. Norwegian Meteorological Institute met.no Diana 1/2 A meteorological visualization and production software Developed at the Norwegian Meteorological Institute, met.no Used operationally since 2001 Also used by researchers Released as open source (GPL 2 license) May 2006 Available from svn.met.no

7. Norwegian Meteorological Institute met.no Diana 2/2 Tailored for operational use in a forecasting environment Small development team in close cooperation with forecasters Fast development cycle - monthly updates Worldwide interest as a result of the open source policy Working to make it more attractive for others Contact e-mail is diana@met.no

8. Norwegian Meteorological Institute met.no New features in Diana NetCDF –Not well tested Bufr observations –WMO templates GRIB through WDB Upgraded to Qt 4 Export to MPEG2 animation Debian package and autotools –Not finished

9. Norwegian Meteorological Institute met.no WDB – Weather and Water database Decode and store meteorological and oceanographic fields Flexible retrieval interface WDB is developed by met.no and SMHI Open source system –based on the PostgreSQL relational database More informations and downloads –http://wdb.met.no/ Presentation about this project tomorrow, by Michael Akinde

10. Norwegian Meteorological Institute met.no Issues with the current production system at met.no Inconsistency between different products Gap between regions Lack of communication between regions Forecasters modify the fields, but we do not know what, where, why...

11. Norwegian Meteorological Institute met.no Solution One gridded database as the basis of all products A group of forecasters will select one model to be the basis for the current session The forecasters from all regions will edit the selected model in a seamless and concurrent manner –Forecasters in all regions will work at the same data –Changes done in other regions will instantly appear –Forecasters can easily see what is modified, by who, why... –Messaging service with instant warnings from system and chatting with other users

17. Norwegian Meteorological Institute met.no Field Edit Objects An algorithm processed on the gridded data inside a geographical area One object defines a specific change in: –One session –One field –One parameter –One time (hour) Traceable (who, where, when, why) Reusable entities (algorithms, not grid values)

18. Norwegian Meteorological Institute met.no Base Objects Defines the algorithm and GUI to adjust input parameters A set of base objects are maintained by a separate application –The forecasters toolbox for field editing –A script language has been developed to define GUI and algorithms –Only a selection of forecasters (administrators) will handle base objects
