Actual version and update policy

ECA&D staff will maintain and update the E-OBS gridded dataset. With the release of version 2.0, we have set up a new registration system which will be used to keep users informed about new versions in the future. If you haven't registered yourself yet as an E-OBS user using this new system, we encourage you to do so here:

 

E-OBS datafiles 1950-01-01 - 2018-12-31

The ensemble version (indicated with a 'e' after the version number) is available on a 0.1 and 0.25 degree regular grid for the elements (daily mean temperature TG, daily minimum temperature TN, daily maximum temperature TX, daily precipitation sum RR and daily averaged sea level pressure PP). They cover the area: 25N-71.5N x 25W-45E. The data files are in NetCDF-4 format. The Global 30 Arc-Second Elevation Data Set (GTOPO30), a global raster Digital Elevation Model (DEM) with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer) developed by USGS is used for the elevation file as well.

The ensemble dataset is constructed through a conditional simulation procedure. For each of the 100 members of the ensemble a spatially correlated random field is produced using a pre-calculated spatial correlation function. The mean across the 100 members is calculated and is provided as the "best-guess" fields. The spread is calculated as the difference between the 5th and 95th percentiles over the ensemble to provide a measure indicate of the 90% uncertainty range. For more details see Cornes et al. (2018) and the guidance on how to use ensemble datasets.

19.0e

March 2019

1950-01-01 - 2018-12-31

E-OBS v19.0e (note the additional 'e') is only available for the ensembe mean and ensemble spread. The 'standard' version is no longer available. The full ensemble can be made available on request. New precipitation series have been included for Sardinia (Italy). Monthly, half-yearly and yearly updates are continued for Germany, Czech Republic, Bosnia and Herzegovina, Norway, Slovenia, Finland, Ireland, Sweden, Luxembourg, Netherlands, Portugal, Spain, Switzerland, France, Denmark, UK and the regional meteorological service of Catalonia (Spain). More detailed information can be found on the page comparing versions 19.0e and 18.0e.

19.0eHOM

April 2019

1950-01-01 - 2018-12-31

E-OBS v19.0eHOM is the version of E-OBS v19.0e based on temperature series that have been homogenized in collaboration with the Horizon 2020 EUSTACE Project. This E-OBS version supports only datasets for daily maximum, minimum and average temperature. Similarly as E-OBS v19.0, these data are only available for the ensembe mean and ensemble spread. Detailed documentation on the homogenization procedure followed can be found in Squintu et al. (2019).

18.0e

November 2018

1950-01-01 - 2018-06-30

E-OBS v18.0e (note the additional 'e') is only available for the ensembe mean and ensemble spread. The 'standard' version is no longer available. The full ensemble can be made available on request. New temperature series have been included for Lombardia (Italy) and updates have been included for Estonia. Monthly and half-yearly updates are continued for Germany, Czech Republic, Bosnia and Herzegovina, Norway, Slovenia, Finland, Ireland, Sweden, Luxembourg, Netherlands, Portugal, Spain, Switzerland and the regional meteorological service of Catalonia (Spain).

17.0

April 2018

1950-01-01 - 2017-12-31

Updates and new stations have been included for Iceland and Israel. Updates have been included for Poland and Romania. Additional series for Sweden have been included. New series for sea level pressure have been included for France. Monthly, half-yearly and yearly updates are continued for Germany, Czech Republic, Bosnia and Herzegovina, Norway, Slovenia, Finland, Ireland, Sweden, Luxembourg, Netherlands, Portugal, Spain, Switzerland, France, Denmark and the regional meteorological service of Catalonia (Spain). More detailed information can be found on the page comparing versions 17.0 and 16.0.
