  1. An inter-operable knowledge data base for regional weather and climate eventsMaya Körber,Andreas Walter,Karsten Friedrich UNECE Expert Forum, 3 September 2015, Geneva

  2. Outline • WMO Climate Watch System • Knowledge Data Base KRONER • Input data • Data model • Data base architecture • Contents • Extreme events viewer • Summary and outlook WMO Regional Association VI Europe and Middle East UNECE Expert Forum, 3 September 2015, Geneva

  3. The WMO Climate Watch System provides advisories and statements to inform users (particularly those involved in natural hazards preparedness, mitigation and response) about evolving or foreseen climate anomalies. UNECE Expert Forum, 3 September 2015, Geneva

  4. KRONER - Knowledge database on EuROpeaNclimatEextRemes • Collection of extreme weather events in Region RA VI • Cold spells, heat waves, heavy rainfall, floods, droughts, wildfires, landslides, snowslides, storms • Data collection establishs relation between weather extremes and related damage • Support of NMHSs with regard to climate watch Data collectioncontents • Approx. 10.000 events, based on varioussources • Description ofevents e.g. bycategoryofevent, begin, end andduration, damage, affectedregion, triggeringpressuresystems, observedanomaliesand extremes, sourceandreferenceof original data, geographicdescription (point, line, polygone) UNECE Expert Forum, 3 September 2015, Geneva

  5. Input data • International Disaster Database (EM-DAT) • Dartmouth Flood Observatory (DFO) • Extreme weather archive (Karlsruhe Institute of Technology, KIT) • Global Disaster Identifier Number Database (GLIDEnumber) Derivedgeographicalinformation • DFO datacontentsgeographicalinformation • Coldspellsandheatwaves: Reanalysisdata NCAR • Drought: Droughtmonitoringof DWD • Heavy rainfall: GPCC • Wildfires: ATSR World Fire Atlas Heat wave August 2003 - Europe UNECE Expert Forum, 3 September 2015, Geneva

  6. Data basearchitecture Webapplication • implemented in PostgreSQL-database with PostGIS expansion • Access via GEOSERVER (WFS/WMS) • Edit events by scripts or with QuantumGIS Maps Tables Reports graphical statistics WFS(EE data) WMS (secondarydata, backrounddata) DWD - Infastructure Geoserver secondaryinformation UNECE Expert Forum, 3 September 2015, Geneva

  8. Frequencyofeventoccurrence Period 1900-2013, 2. projectphase automatically collected manually collected UNECE Expert Forum, 3 September 2015, Geneva

  9. Extreme Events Viewer - Extreme events in 2007 UNECE Expert Forum, 3 September 2015, Geneva 9

  10. Extreme Events Viewer - Details UNECE Expert Forum, 3 September 2015, Geneva 10

  11. Extreme Events Viewer - Statistics UNECE Expert Forum, 3 September 2015, Geneva 11

  12. Extreme Events Viewer - Statistics UNECE Expert Forum, 3 September 2015, Geneva 12

  13. Summary and outlook • Already extensive data sets in various data collections available including information about damage and loss • Merging different information sources and adding geographical information to allow regional searches • Fewer data available with extended observation period → systematic collection of events desired • Data access via webclient (NMHSs) • Export- and statistical functions • Particular attention to knowledge database within WMO TT-DEWCE • Possible spatial extention in future projects (e.g. Africa) UNECE Expert Forum, 3 September 2015, Geneva 13
