  1. “Building the daily observations database for theEuropean Climate Assessment”Albert.Klein.Tank @ KNMI.nlCLARIS meeting, 7 july 2005

  2. Guide: • European Climate Assessment project • Daily observations database • Current activities • Take away messages

  3. Guide: • European Climate Assessment project • Daily observations database • Current activities • Take away messages

  4. The ECA project: • initiated by EUMETNET in 1998; coordinated by KNMI • at present 43 participants (data holding institutions) from 39 countries (WMO-RA VI) • station data is collated and processed at KNMI • joint report issued in 2002; next report in 2006 • results have been used for impact studies (e.g. EEA)

  5. Guide: • European Climate Assessment project • Daily observations database • Current activities • Take away messages

  7. Daily observations database: • at present over 300 station series(TX,TN,TG, RR starting 1950 or earlier) • same quality control procedures applied to all series • four common homogeneity tests applied to all series • core set of extremes indices calculated • joint paper describing the ECA dataset published inInt. J. of Climatol, 2002 • contribution to GCOS Surface Network andworldwide analyses of extremes by CLIVAR/WMO

  8. http://eca.knmi.nl • public website presents: • about 75% of the daily series for free download in ASCII and DODS • all indices results including time series plots and trend maps • note that all software we used is public domain(database: MySQL statistics: R web logics: PHP)

  10. Guide: • European Climate Assessment project • Daily observations database • Current activities • Take away messages

  11. The ECA&D project: • fill gaps & update series using SYNOPs from GTS(enables monitoring type of products) 1900 2004 interrupted station series nearby station SYNOPs blended series

  12. The ENSEMBLES project: • the daily observations database of ECA is considerably extended and improved in the ENSEMBLES-EU-FP6 project (ENSEMBLE-based Predictions of Climate Changes and their Impacts) • a daily gridded dataset is produced for Europe at20x20 km2 resolution for comparisons with regional models, impact studies, etc. (due September 2007)

  13. Guide: • European Climate Assessment project • Daily observations database • Current activities • Take away messages

  14. Take away message: • joint work on the data and maintenance is crucial for success: frequently update series and indices results, continue data QC and homogeneity analysis • the ECA platform, which is now also used as the basis for the ENSEMBLES grids, has proven to be suitable for easy data access, indices calculations, and inclusion of new monitoring products • CLARIS participants are welcome to use ECA software, source code, expertise, etc.
