The EUMETNET postprocessing (PP) module has just published its first dataset paper to date in `Earth System Science Data <https://www.earth-system-science-data.net/>`_. | ||
|
||
This paper is about EUPPBench, the first version of an open postprocessing benchmark dataset which can be used in many different ways by the scientific community | ||
to benchmark new and old postprocessing methods. This dataset and the description article are the result of the hard work of the many module participants. | ||
|
||
The dataset includes both gridded and station-point ECMWF forecasts along with the observations, time-paired together to obtain an 'analysis-ready dataset' that | ||
can be used directly by the statistical and machine learning community. | ||

|
||
Many past forecasts (reforecasts) are also included to enable training of postprocessing algorithm, representing 20 years of data. | ||

|
||
The gridded observations corresponding to the gridded forecasts have been obtained by using the ERA5 reanalysis data (see https://climate.copernicus.eu/climate-reanalysis) | ||
and cover a portion of central Europe. The station data include forecasts and observations of 100+ stations inside this domain. | ||

||
On the practical side, the recommended way to download the data is through a ECMWF climetlab plugin (available at https://github.com/EUPP-benchmark/climetlab-eumetnet-postprocessing-benchmark), | ||
returning xarray datasets which can then be used directly or converted to netCDF files. But other ways are possible, see the Supplementary Information in the paper. | ||
|
||
The data are stored on the ECMWF European Weather Cloud (EWC). Many thanks to them for their support. | ||
|
||
Many more scientific activities will be organized in the future around this dataset, so stay tuned if you are interested ! | ||
Our wish with the PP module participants is that this first step will foster many interesting developments in the field of postprocessing | ||
and verification of weather forecasts in the future. | ||
