ERA5 model level data location: /glade/collections/rda/data/ds633.6/e5.oper.an.ml
Some notes about Isla's environment issues: Geocat needs metpy 1.4.0. When I specified metpy to be 1.4.0 though then xesmf didn't work. I needed cf_xarray to be updated to 0.7.2. I did this by conda update cf_xarray
Not sure why any of this was necessary. It seems like this should have happened automatically.
