Here we use Fsspec ReferenceFileSystem to read data from 300 NWM Forecast netcdf files on AWS Public Dataset as a single virtual dataset. We used tau=0 for each forecast in the past + the latest forecast to construct the best time series virtual dataset. The only new file we created was the JSON file that points to the original NetCDF files. We read that JSON with the Zarr library.
