Tested on Hera. It works fine.

I left several suggestions for clean up below, but we definitely need to make sure that we aren't pointing to unsupported data paths before merging.

[christinaholtNOAA]

One more tiny change request, but the changes look good.

It looks like the supported radar obs paths are here:

Jet: /public/data/radar/mrms
Hera: /scratch2/BMC/public/data/radar/nssl/mrms/conus

@mkavulich Might find this useful for his work with data retrieval, too.

@christinaholtNOAA Note that those are paths for realtime forecasts only. You can find the full list of observation paths for realtime/retro runs in this commit for hera/jet/wcoss2: obs data paths

LGTM.

@MichaelLueken In our RRFS dev merge discussion yesterday we chatted about pushing this one through when it's ready. If we can go ahead with that, it would be helpful. Thanks!

[MichaelLueken]

@danielabdi-noaa I'm working on reviewing and testing this PR now. It looks like there is a conflict in ush/config_defaults.yaml. Please merge develop into your feature/task_radarref branch one more time and I will approve this work and kick off the Jenkins tests. Thanks!

[danielabdi-noaa]

@MichaelLueken I have resolved the conflicts. You can kick off the Jenkins tests now.

[MichaelLueken]

@danielabdi-noaa These changes look good to me! The necessary components to run this task and the process bufr task will be completed in PR #725. Approving now.

[MichaelLueken]

The Jenkins tests have completed. The Hera Intel tests failed. Manually running them, all tests successfully passed (with the exception of grid_RRFS_CONUS_25km_ics_FV3GFS_lbcs_RAP_suite_HRRR, which failed due to issue #688). Moving forward with merging this work now.
