The path for chrtout_file provided in both usage_example_streamflow_timeseries.ipynb and usage_example_rerechunk_chrtout.ipynb notebooks is on GLADE ('/glade/p/datashare/ishitas/nwm_retro_v2.1/chrtout.zarr'), which I don't have access to it!
The following command works for loading version 2.0 from s3 ('s3://noaa-nwm-retro-v2-zarr-pds'), but it fails with KeyError: '.zmetadata' for version 2.1 ('s3://noaa-nwm-retrospective-2-1-pds')!
# url = 's3://noaa-nwm-retro-v2-zarr-pds' # version 2.0
url = 's3://noaa-nwm-retrospective-2-1-pds' # version 2.1
ds = xr.open_zarr(fsspec.get_mapper(url, anon=True), consolidated=True)
Do you know how I can read version 2.1 and retrieve timeseries for a given feature_id?
