@lassiterdc, in your example above, f_in_ncs is just a string and you are passing this string to xr.open_mfdataset() which i don't think knows what to do with it.

python f_in_ncs = "data/"

have you tried retrieving the list of all files under "data/" via the glob module?

```python import glob f_in_ncs = sorted(glob.glob("data/*.nc"))

mf_ds = xr.open_mfdataset(f_in_ncs, concat_dim = "time", chunks={'outlat':3500, 'outlon':7000, 'time':50}, combine = "nested", engine = 'netcdf4') ```
