The user guide now has an example of a wind retrieval, with only two sections of the first User Guide left to complete. In addition I have also added the ability to use linear interpolation to map the HRRR grid to your PyART Grids for a smoother wind field to constrain against, removing artifacts that were being generated at the HRRR grid point boundaries.
Downgrading pyproj seems to make the doc build actually work. On my Mac, pyproj=3.4.1 triggered a missing library error, so holding the doc build environment to pyproj=3.3.
