Welcome to the website of the European Climate Assessment & Dataset project. Presented is information on changes in weather and climate extremes, as well as the daily dataset needed to monitor and analyse these extremes. ECA&D was initiated by the ECSN in 1998 and has received financial support from the EUMETNET and the European Commission.


What's new?


The database is updated until: Feb 28, 2018.

February 2018 - Series for sea level pressure, relative humidity and wind speed have been included for France (kindly provided by Météo-France).

February 2018 - Use statistics of the ECA&D webpages and E-OBS are now available.

January 2018 - Due to a bug, part of the temperature and precipitation series for Sweden were not included. This has been corrected.

January 2018 - Updates until the end of 2016 of 23 stations are kindly provided by the Romanian National Meteorological Administration.

November 2017 -Updates until the end of 2016 of 33 stations are kindly provided by the Polish Institute of Meteorology and Water Management (IMGW). Following the changes in the data policy of the Institute of Meteorology and Water Management, their provided series now have the status "downloadable".

ECA&D forms the backbone of the climate data node in the Regional Climate Centre (RCC) for WMO Region VI (Europe and the Middle East) since 2010. The data and information products contribute to the Global Framework for Climate Services (GFCS).


Participants and data

map of participating countries

Today, ECA&D is receiving data from 68 participants for 63 countries and the ECA dataset contains 44742 series of observations for 12 elements at 10613 meteorological stations throughout Europe and the Mediterranean (see Daily data > Data dictionary). 78% of these daily series can be downloaded from this website for non-commercial research and education and ECA&D and the gridded dataset E-OBS enjoy widespread use in Europe. Participation to ECA&D is open to anyone maintaining daily station data. If you want to join please contact us. See our data policy for more details.


E-OBS gridded dataset

E-OBS image

E-OBS version 16.0 has been released. E-OBS is a daily gridded observational dataset for precipitation, temperature and sea level pressure in Europe based on ECA&D information. The full dataset covers the period 1950-01-01 until 2017-08-31. It has originally been developed and updated as parts of the ENSEMBLES (EU-FP6) and EURO4M (EU-FP7) projects. Currently it is maintained and elaborated as part of the UERRA project (EU-FP7).
