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

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

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)
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
•

Current activities
•
ECA&D forms a WMO Regional Climate Centre (RCC)
node on data now
www.ecad.eu
•
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 EUEUPORIAS
