Explore the National Water Model Reanalysis

Use Xarray, Dask and hvPlot from the HoloViz tool suite to explore the National Water Modle Reanalysis Version 2. We read from a cloud-optimized Zarr dataset that is part of the AWS Open Data Program, and we use a Dask cluster to parallelize computation and reading of data chunks.
