1 Assessing progress on Data Coordination (WP1.3) Manola Brunet, Dimitrios Efthymiadis, Alba Gilabert Centre for Climate Change, University Rovira i Virgili, Tortosa/Tarragona, Spain 3rd General Assembly, Zurich, Switzerland, 2-4 April 2012

2 Outline for Data Coordination and access to national archives Gathering/using historical sources for digitisation and problems faced Digitisation: status and prospects Data development (QC & homogenisation): status and future actions Data exchange exercise: ensuring the development of long records (insights and constraints)

3 Gathering/using historical sources for digitisation and problems faced Worldwide on-line repositories (e.g. CDMP, BADC) employed (see details in Annual reports and Brunet et al. 2012 under review) Further availability of scanned data from Meteo-France (good coordination) and the Italian NMS and the Ebro Observatory Library Gathering digitised data from other efforts/projects (e.g. AEMet, the ECA&D, CIRCE and MILLENIUM projects and the ISPD initiatives) Problems faced with scanned sources and actions to overcome them: Some of the sources (e.g. CDMP historical data) have problems with scans readability (i.e. poor scanning, missing headers and pages, duplicated pages) Visual cross-checking sources/digitised data essential to spot out problems and improve digitisation Need for preserving the original sources (scans: a poor and short- lasting preservation media and impossibility of ensuring a 100% perfect scanning work) Transferring to CDMP managers the problems encountered with the on-line sources and the digitisation effort made to avoid duplication from other users

4 Digitisation: status and prospects. 51 Tx/Tn daily records & approximate length

5 Digitisation: status and prospects. 53 RR daily records & approximate length

6 Digitisation: status and prospects. 30 SLP hourly (~ 3 obs/day) records & approximate length

7 A general look at the digitisation effort

8 A more complete view of the whole effort: temperature records 2011 2012

9 A more complete view of the whole effort: precipitation records 20112012

10 A more complete view of the whole effort: SLP records 20122011

11 Data development (QC): status and future actions QCing digitised data: a double approach Ensuring correspondence between scanned and digitised data (visual cross-checking) Applying RClimDex extra-QC About 60% of data already QCed. Worth exercise: identifying problems with sources & making more efficient the digitisation task Next: applying the QC to the remaining series & the new digitised

12 Data development (QC): status and future actions

13 Data development (homogenisation): future actions To be undertaken once finished the digitisation & QC efforts (from Sep onwards) and after merging the series Application of three homogenisation methods (C3-SNHT, ACMANT & HOMER) Countries where the homogenisation exercise could be applied: Algeria, Libya, Morocco, Jordan records

14 Data exchange exercise: merging recent with ancient parts of records (insights and constraints) Several lines of action: Ensuring currently available climate records (e.g. from ECA&D & other digitisation efforts: CIRCE) can be extended back in time further Accessing/engaging data producers (NMHS) and enabling exchange of data between NMHS and EURO4M: recent observations merged with past digitised measurements Steps taken: Personal requests to several PRs within WMO thanks to the 16th WMO Congress (May 2011): Morocco, Algeria, Tunisia, Egypt under the MEDARE umbrella Submission of official requests through MEDARE to all the countries Using the ECSWA WS in Casablanca (March 2012) for ensuring exchange

15 Data exchange exercise: merging recent with ancient parts of records (insights and constraints) Positive responses so far: Algeria, Libya, Cyprus, Lebanon, Jordan Already defining protocols with Libya and in their way with other countries. Tricky exercise… big reluctance to share in the region, even among them Data sharing constrained to MEDARE, so far, but for use in EURO4M analyses also The next MEDARE WS (Turkey, June 2012) aimed at defining the national networks that will take part of the MEDARE data base and preparing the MEDARE side- event at the WMO extra-Congress (Oct 2012)

16 Dimitrios following up with our approach for developing long time-series
