Merging cutouts / Integrate downloaded SARAH data into existing ERA-5 cutout

[euronion]

Hi there,

Unfortunately we don't support that functionality. Whenever you prepare a feature involving ERA5, the data is downloaded again.

It might be possible to merge the underlying netCDF files and data, but since we process the datasets, do grid, temporal alignment and interpolation during the interpolation step, this is rather complicated and error prone.

What you can do, is built a second cutout based only on SARAH data for the features="influx" , by passing this to the .prepare(...) function. That feature does not require any downloads of ERA5 data.

P.S.: If the mailing list request is not accepted, you can also try the discord server.
