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, 2017.

January 2017 - While the global annual mean air temperature is likely to reach its highest level in 2016 (based on a provisional report by the WMO, the annual mean air temperature anomaly across Europe for 2016 was not record-breaking but ranks 6th in the list of warmest years in the series since 1950. See the Climate Indicator Bulletin for details.

January 2017 - Updates have been included for Hungary up to the end of 2015, kindly provided by the Hungarian Meteorological Service.

December 2016 - Updates have been included for Israel including some data for the first half of the 20th century, kindly provided by the Israel Meteorological Service.

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 64 countries and the ECA dataset contains 43162 series of observations for 12 elements at 10582 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 gridded dataset

E-OBS image

E-OBS version 14.0 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 2016-08-31. 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).
