Preprocessed impact-relevant variables - ERA5 for unseen-awg simulations

Wider, Jonathan; Zscheischler, Jakob

Dataset
Summary
This dataset contains impact-relevant variables at a daily scale over Europe:
- Liquid water equivalent thickness of total precipitation amount
- Mean temperature at 2 metres
- Maximum temperature at 2 metres
- Minimum temperature at 2 metres

The 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:
- Units were converted, we enforce non-negative total precipitation amounts
- The data were regridded to a 0.4° resolution grid over Europe using bilinear or conservative regridding. The latter is employed for total precipitation amounts
- 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.
