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 79 participants for 66 countries and the ECA dataset contains 74209 series of observations for 13 elements at 20120 meteorological stations throughout Europe and the Mediterranean (see Daily data > Data dictionary). 76% of these daily series can be downloaded from this website for non-commercial research and education. 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 version 22.0e 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 2020-06-30. It has originally been developed and updated as parts of the ENSEMBLES (EU-FP6), EURO4M (EU-FP7) and UERRA (EU-FP7) projects. Currently it is maintained and elaborated as part of the Copernicus Climate Change Services.
