Description

Other forcing sources that we could support include HRRR, WARFS, MRMS, ERA5, NLDAS, Stage4, IMERG (the last 3 have already been converted to Zarrs by Parth Modi). This issue can be split up into subissues for each source if we want.

Contributor guide

Research direction
Examine the existing forcing source implementations (e.g., NLDAS, Stage4) and replicate the pattern for new sources like HRRR, WARFS, MRMS, ERA5, IMERG. Coordinate with Parth Modi for Zarr conversions.
