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.

A problem in the UK was discovered due to the fact that TX and TN are swapped in 2013 and 2014 which is fixed in this version.

July 2016

1950-01-01 - 2015-12-31

There was a problem with the sea level pressure series of some stations in Croatia and Italy resulting in strange features in the gridded sea level pressure fields (pp) for E-OBS v13.0. These have been corrected and the gridded fields are released again as v13.1. The temperature and precipitation files are the same as for v13.0. New stations are included for the north of Norway, Czech Republic and Portugal. Re-inclusion of Danish series and updates for several other countries. More detailed information can be found on the page comparing versions 13.0 and 12.0.

9.0

October 2013

1950-01-01 - 2013-06-30

An artefact in the drizzle occurrence, observed in the rotated grid, was solved by a modification of the regridding procedure. This modification restricts the selection of the number of 0.1 degree grid points of the master grid contributing to each grid point in all rotated versions.

8.0

April 2013

1950-01-01 - 2012-12-31

Increased station density in the Mediterranean and Russia. Various series are updated. Note: there is still a slightly sparser coverage over Scandinavia approx. before 1961 although less than in version 7.0. This is related to a problem in the gridding algorithm.

7.0

September 2012

1950-01-01 - 2012-06-30

Irregularities around Luxembourg (precipitation) and Romania (min & max temperature) are corrected. Increased station density in Sweden and Finland, and various series are updated. Note: there is a sparser coverage over Scandinavia approx. before 1961 despite the higher station density. This is related to a problem in the gridding algorithm.

1950-01-01 - 2009-12-31

1950-01-01 - 2008-12-31

Station density increased in Norway, the Netherlands, Germany, Northern Italy and Serbia. More series are used due to the upgrade of the programs to produce the underlying station series (More information).
