What didn't work:

python f = fsspec.filesystem("s3", anon=False) with f.open("some_bucket/some_remote_destination.nc", mode="wb") as ff: xr.open_dataset("some_local_file.nc").to_netcdf(ff)

this results in a OSError: [Errno 29] Seek only available in read mode exception

Changing the above to

python with fsspec.open("simplecache::s3://some_bucket/some_remote_destination.nc", mode="wb") as ff: xr.open_dataset("some_local_file.nc").to_netcdf(ff)

fixed it.

How would you go about reading this file? Once it is saved in s3

Im currently getting an error ValueError: b'CDF\x02\x00\x00\x00\x00' is not the signature of a valid netCDF4 file
