These data can be used to develop ERA5-based unseen-awg weather generators, or as in baseline dataset to compare generated data against. The following preprocessing steps were applied to the retrieved daily ERA5 data: - Geopotential height at 500hPa was computed from geopotential at 500hPa - The data were regridded to the coarse resolution grid over Europe and the North Atlantic (2.5° horizontal resolution) used for computing analogs - Format and metadata were harmonized to fulfill the requirements of unseen-awg. This includes the creation of "dummy-dimensions" ensemble_member and lead_time Once the zip files in this dataset are expanded, they combine to form a single .zarr archive that can be used within the unseen-awg framework. All partial files must be downloaded and extracted, otherwise the .zarr store will contain missing data.
