"In this notebook we'll be working with AORC v1.0 meteorological forcing. These data are publicly available for the entire CONUS, spanning from 1980 to 2020. Kerchunk header files have been created by the Alabama Water Institute team and this is an ongoing project. Please note that this jupyter notebook works for data within 2007-2019, but it cannot work with data prior to 2006. "

This issue is probably three issues in one:

• Incorporate a connection to the newly released NWM 3.0 retrospective forcings (developed from the AORC 1.1 dataset)
• Incorporate the Teehr library into the forcing subsetting capability
• Extend the input to work with the latest hydrofabric.

Additional description forthcoming...
