I have to download GFS or ERA data once again when I interrupt the process?

When I interrupted the forcing data processing, the GFS or ERA-5 data have to been downloaded once again, the historic downloaded data cannot be read? The downloading elapsed time sometimes is long.

I'm just a pyschism user, so I don't know the full details of the implementation; my understanding is that there's no caching mechanism for partially downloaded meteorological forcing files. At least ERA5 doesn't seem to have it. GFS has 3 different implementations, but I still think they don't have that functionality

The downloaded data was saved to a temporary folder created by tempfile.TemporaryDirectory(). After generating sflux files, this folder will be deleted.

Downloading ERA5 has been slow in the last couple months because they are in a transition to a new API which caused the longer queueing time.
