E-OBS v19.0HOM gridded dataset

This is the E-OBS gridded dataset version 19.0eHOM which 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.

 

E-OBS datafiles

The ensemble version (indicated with a 'e' in 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 and daily maximum temperature TX). 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.

Access to underlying station dataset

Klok and Klein Tank (2008; see publications) describe the ECA&D station dataset that has been used for the gridding. The station dataset that serves as a basis for this E-OBS version can be downloaded (for the part of the dataset for which national datapolicies allow this).
