Data formats Open/standard formats  Observations: Bufr  Fields: NetCDF – Possible to convert from Grib to NetCDF Internal met.no formats  Satellite and Radar: miTiff – Tiff with a geographical header Norwegian Meteorological Institute met.no

Where is Diana used/planned to be used • Norway – The Norwegian Water Resources and Energy Directorate (NVE) – Norwegian Geotechnical Institute (NGI) – University of Bergen – University of Oslo – Storm Weather Center (Commercial weather services) • Sweden (Agreement) • Latvia (MoU) • Estonia (Hirlam and bufr obs) • Lots of other contacts, status unknown Norwegian Meteorological Institute met.no

Current development • Make it easier to install Diana • More standard formats – Reading from WDB (dataBase) • Improved field editing Norwegian Meteorological Institute met.no

WDB - Weather and Water Database • Decode and store meteorological and oceanographic forecast 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/ Norwegian Meteorological Institute met.no

Field corrections • A part of Diana • Corrections realized through reusable and traceable entities • Selection of affected area • Algorithm and GUI defined using script language • Instant visualization of changes • Spacial smoothing • Topographic and land/sea masking • Interpolation in time Norwegian Meteorological Institute met.no

Summary • Diana, Tseries and WDB are free to use, available under the GPL license • We hope that other institutions will use these programs and contribute to the further development Norwegian Meteorological Institute met.no
