Weather Data¶

Cutouts are spatio-temporal subsets of the European weather data from the ECMWF ERA5 reanalysis dataset and the CMSAF SARAH-3 solar surface radiation dataset. They have been prepared by and are for use with the atlite tool. The tutorial uses a smaller cutout than required for the full model (30 MB), which is also automatically downloaded.

There are two ways to obtain cutouts:

Retrieve pre-built cutouts from the archive using the retrieve_cutout rule (default). This downloads ready-made cutouts from data.pypsa.org.
Build cutouts from scratch using the build_cutout rule. This requires access to the CDS API to download ERA5 data directly.

For building your own cutouts, see build_cutout and the atlite documentation.

The following pre-built cutouts are available for download under https://data.pypsa.org/workflows/cutout/<version>/<cutout>.nc (click on a cutout name below to download directly).
