RA-VI 16, Helsinki, Sept DWD observation network model (II)  Secondary network  precipitation stations (with voluntary observers: automated, conventional)  wind measuring stations (secondary stations: automated)  phenological observer network (voluntary observers)  Additional network  mobile measuring units  partner networks  Aircraft measurements (AMDAR) Key Area: Design, planning and optimized evolution

RA-VI 16, Helsinki, Sept Stations operated by Deutscher Wetterdienst  4 Regional Oberserving Network Groups Hamburg, Potsdam, Offenbach, Munich  65 Stations with professional observers, 35 occupied UTC, 30 only daytime 48 measuring radioactivity (air+precipitation) 28 RBSN Stations 11 Climate Reference (traditional equipment) 4 GSN-Stations (GCOS) 1 GUAN Station 1 GAW Station  114 Automated Weather Stations  17 Weather Radar Stations  9 Aerological Stations  4 Wind Profilers  +34 Stat. as part of Bundeswehr Geoinfo Service Key Area: Design, planning and optimized evolution

RA-VI 16, Helsinki, Sept Additional Stations operated by DWD and Partners  1781 Voluntary Stations (climate; wind; precip), 1365 reporting online (24/1 reports per day) Ship-based:  740 Voluntary Observing Ships (VOS)  19 Ship AWS (24 reports/day) Last but not least …:  1292 Phenological stations (observing plants)  1500 Partner stations (approx) (motorways, fed.states, wind-energy, (nuclear) power-plants, universities, military) Key Area: Design, planning and optimized evolution

RA-VI 16, Helsinki, Sept technical monitoring data monitoring Monitoring System and Quality Control to improve and assure the quality of the data Monitoring and Quality Control Key Area: Integrated observing system operation

RA-VI 16, Helsinki, Sept Tools and views for technical Monitoring Number of station requests per minute Number of SYNOPs produced per minute Key Area: Integrated observing system operation

RA-VI 16, Helsinki, Sept Quality control  quality control of data  step 1:automated quality control at station (realtime)  step 2: automated quality control at central database (realtime); semi-automated quality control in central office (near realtime) (software tool „QualiMET“ - central version)  Monitoring 24/7 since 2012/01  step 3:semi-automated quality control at DWD‘s regional network groups (software tool „QualiMET“; data processing after max. 10 days)  step 4:semi-automated quality control of the values at the climatological observation times in central office (data processing within 2 years)  each dataset will be flagged with a quality level  each value will be flagged with different quality information Key Area: Integrated Quality Management

RA-VI 16, Helsinki, Sept Verification procedure QualiMET ( 5 stages) Key Area: Integrated Quality Management

RA-VI 16, Helsinki, Sept Climatological reference stations  To avoid wrong interpretation which is caused in the automatic measurements  Conventional measurements for 10 years  3 measurement per day: 06:30, 13:30 and 20:30 UTC  11 stations are selected, each is representative for a special area of Germany  To improve methods for homogenization of climate time series and data generation Brocken: Climatological reference station Key Area: Integrated Quality Management

RA-VI 16, Helsinki, Sept Key Area: Data and metadata management Principles for Metadata at DWD

RA-VI 16, Helsinki, Sept METADATA as a source for operative usage in DWD WebShop ( data and more) KU 2/NCDC National Climat. Monitoring KU 1 Climate Consultancy. GPCC Meta-DATA. Weste Climatological Products. MPG generating reports (FM94,FM12,FM71) QualiMET QualityAssurance Phaenlogical ONLINE MAP s with Various Layers Payments ( voluntary) MODES Online-Stations ANKONDA WebApplication Voluntary ANKONDA WebApplication Voluntary ILM Station- Management FE Assimilation WMO Pub9VolA NinJO.Data+Product Visualisation Key Area: Data and metadata management

RA-VI 16, Helsinki, Sept Typical trouble with metadata  No information about changes at a station  Inconsistency between dependent sources (i.e. elevation…)  Lack of synchronization with offline-procedures  Especially Lat./Lon. different various formats (dez.,°,min/sec)  4 sources / 5 different values ;-) …. Which is ‚the best‘  Representation of a complicated history for a time-series  standard exchange format + automated process is necessary! Key Area: Data and metadata management

RA-VI 16, Helsinki, Sept Amount of station Metadata Overview of the contents [count of largest categories in thousands]:  WMO Main Stations (GSN, RBSN, RBCN ….)  Airports (with ICAO loc.ind.) reporting METAR/SPECI  German additional stations (voluntary, federal states)  Related partners (roads, renewable energy ….)  Voluntary observing ships and other marine vessels  Additional GPCC stations of all countries  Currently counting over all: Key Area: Data and metadata management

RA-VI 16, Helsinki, Sept Results  WIGOS is part of the current DWD strategy  Implementation of the ten WIGOS key areas is mainly realized in DWD  DWD will be the national integrator for meteorological observations and meta data  Standardization of observations is realized in all meteorological networks of DWD (baseline network, secondary (= voluntary) network)  European standardization in marine network started in last year  Integration of additional partnership networks is planned
