  1. Marine Climate Monitoring relevant to WMO / CCl DWD in Hamburg Seewetteramt Christiana Lefebvre Section: Marine Climate Monitoring

  2. Content: International Marine Meteorological Involvement International Exchange of Marine Meteorological Data (Marine Climatological Summary Scheme) Modernization of MCSS Historical Data from Logbooks

  3. International Marine Meteorological Involvement JCOMM- Joint WMO/IOC Technical Commission for Oceanography and Marine Meteorology

  4. International Marine Meteorological Involvement EUCOS - EUMETNET Composit Observing System EUCOS aims to establish and operate a truly European observing network leading to better-quality numerical and general forecasts, initially on a European scale. Marine Component of the EUCOS Operational Programme: E-SURFMAR E-ASAP VOS Deutscher Wetterdienst is responsible member of the EUCOS Programme Phase 2007-2011 Data Buoy DB-TAG DB-TAG VOS-TAG

  5. International Exchange of Marine Meteorological Data WWW: World Weather Watch MCSS: Marine Climatological Summaries Scheme

  6. Port Meteorological Office Rostock Hamburg Bremerhaven Stock in Rotterdam Stock in Neuseeland

  8. Spatial Distribution of VOS Observations

  9. GCCs ensure, that WMO agreed Minimum QC Standards are applied and feed back results to CM All data received by GCCs is distributed to 8 RMs quarterly VOSClim ship data is submitted to DAC At the year end a ‘GCC Annual Report’ is published highlighting GCCs work and data received GCCs provide advice/support to CMs The Tasks of the GCCs

  10. Results from GCC‘s Annual Report 2008

  11. Results from GCC‘s Annual Report 2008

  12. Archiving of Marine Meteorological Data at DWD • DM – VOS Data • Real-time VOS Data via GTS • Data from Platforms or moored Buoy Data via GTS • Data from drifting Buoy via GTS

  13. VOS Data Archive at DWD

  14. High Quality Control of VOS Data at DWD • On-land Position Check • Time-sequence Check • Comparisons of different Parameters with a Climatology • Manually correction of data errors

  15. MARDAB - Marine Data Base • Archive of statistics for all between 77.0 N bis 60.0 S for the period 1951 – 2000 and for decades • Means, extremes, frequency distribution (1- , 3-dimensional), variance of different elements as • wind, waves, mean sea level pressure, temperatures (TL, TW, TD), • visibility, cloud cover, rel. humidity, evaporation • About 1200 Sea Areas of 5° x 5°, partly 2,5° x 2,5° or 10° x 10 ° • Basis: • - About 51 millions of observations of the VOS fleet • - quality controlled data by using HQC (flags) • - elimination of the port problem due to use of automatic stations

  16. Monitoring Products Monthly Air Temperatures and Anomalies across the North Atlantic Ocean http://www.dwd.de/

  17. Marine Climatological Summaries Regulations for the presentation of the MCS: • decadal periods • chart form (Mercator projection) for the area of responsiblity • unit areas of 5° x 5° squares • tabular form • order of presented data • monthly and annual charts • tabular form for fixed stations • and representative areas • no financial support by WMO N o l o n g e r ‚S t a t e o f t h e A r t‘

  18. Modernization of MCSS ETMC established 2 Task Teams in 2007: • Task Team on Delayed Mode VOS Data (TT-DMVOS) • Task Team on Marine and Oceanographic Climatological Summaries (TT-MOCS)

  19. Main Topics of the TT-DMVOS / TTMOCS Planning Meeting 2008 • Future Data Flow • Higher Quality Standards (HQCS) • Revisions of IMMT and Minimum Quality Control Standards (MQCS)

  20. Draft for the Future Marine Data Flow

  21. Historical Data from Logbooks DWD holds an Archive of 7796 met. Journals from Sailing Ships and about23768 met. Journals from Steamers

  22. Archive of Historical Data from Logbooks since 1830

  23. Digitization of the Historical Data: Project HISTOR HISTOR aims in: • Providing quality controlled historical Data • Providing Metadata • Preserving the content of the logbooks by imaging

  24. State of the historical Archive Σca.21.4 million
