1. International Climate Assessment & Dataset Peter Siegmund, Albert Klein Tank, Ge Verver KNMI, Netherlands ET DARE meeting, WMO, 3-6 November 2014

2. European Climate Assessment & Dataset (ECA&D)
Started in 1998
Regional co-operation between 62 countries in Europe
Brings together daily station records (historical and contemporary) in a central repository
Pragmatic approach; country-specific data policies respected
Harmonized metadata and data QC / homogeneity testing procedures

4. Example: Flooding in Central Europe, May/June, 2013

9. Conclusions I
ICA&D regional data repositories and web portals are developed for daily data obtained from national databases in a region
Most daily data series did not exist in international archives yet
Products are relevant for national, regional, and global analyses and assessments (contributions to ISPD, GHCN-D, GPCC, ISTI, ETCCDI)
Gridded fields are produced when station coverage is satisfactory
Recovered and digitized data is added when available
Capacity development is the key success factor
ICA&D is selected as GFCS high priority project 8 (total of 9)

10. Conclusions II
Data policy issues are partly circumvented because derived indices/indicators are more readily shared and released than daily observational records themselves
All data and products are restricted to non-commercial research and education
Challenge of finding an institution which can commit the resources and responsibility to host an ICA&D system
Thank you…

12. Current activities
ECA&D forms a WMO Regional Climate Centre (RCC) node on data now
Monthly updates produced as part of the EU-projects EURO4M and UERRA
Digitized data for the Mediterranean (URV Centre for Climate Change) included as part of EURO4M
Extension to sub-daily data (hourly and 6-hourly) developed as part of UERRA
Core set of ETCCDI climate change indices calculated for grids as part of EU- EUPORIAS
