Issue with build_cutout using alite

@Rock910, creating new cutouts usually needs some extra attention. Did this Sarah example work for you? I can also recommend testing the ERA5 cutout if you haven't tried yet.

Hi @Rock910 ,

Building the cutouts is a tedious task. For ERA5 the data can be downloaded automatically as long as you have registered with the CDSAPI. For SARAH data (and creation of the SARAH cutout), you have to download the raw SARAH data first and pass the raw data folder to PyPSA-EUR via this line in the config.yaml:

      sarah_dir:

Right now it is empty (in your config above). Empty means NULL, and that creates the error you see.

Thank you for your reply, would there be any way to have a prebuilt SARAH cutout for the year 2016 instead? I was trying to get the data but it looks like the total size is 7.5 TiB.

I can't offer you a prebuilt cutout for 2016.

The SARAH data should not be 7.5 TiB, you might have selected the wrong product or maybe you did not limit the temporal range for which to download the raw data.

If you select the right product and limit the temporal range for which you download the variable, you end up with a more reasonable 98 GiB of size for the raw data, see here:

Hi @Rock910

Did you have success with downloading and building a SARAH cutout?
