Abstract
This use case demonstrates how to generate and share Kerchunk references for tens of thousands of NetCDF files from the CONUS-wide National Water Model (NWM) outputs. Leveraging recent HydroShare modernization efforts, the workflow enables efficient, scalable access without converting files to Zarr. The shared resource includes both the Kerchunk outputs and a reproducible notebook, allowing users to either access subsets of NWM data or learn how to apply the same method to their own large-scale datasets. This example highlights HydroShare’s evolving capabilities in supporting FAIR, cloud-optimized hydrologic data workflows.
