Today, ECA&D is receiving data from 62 participants for 62 countries and the ECA dataset contains 37162 series of observations for 12 elements at 7860 meteorological stations throughout Europe and the Mediterranean (see Daily data > Data dictionary). 61% 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 gridded dataset

E-OBS version 9.0 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 2013-06-30. It has originally been developed as part of the ENSEMBLES project (EU-FP6) and is now maintained and elaborated as part of the EURO4M project (EU-FP7).
