Gerard and I would like to work on this during the next couple weeks. We can work in our NCAR fork of UFS_UTILS and then issue a PR to the NOAA_EMC UFS_UTILS authoritative repo, if that sounds good.

I think everything is working. Using cd0aafc on Hera, I created a C96 uniform global grid. The 'oro' and 'surface' files had the required geo-referencing records. I was able to add a map background when viewing them with 'ncview'. I fed the 'oro' and 'surface' file into chgres_cube for a Feb 2, 2020 test case. It ran without issue. And the files output from chgres_cube had the required geo-referencing records, which were recognized by 'ncview'. All files were then fed to the forecast model, which ran successfully for a 24-hour forecast.

After the reviewers gave their blessing, the branch at a3ea604 was compiled on Hera, Jet, Dell and Cray. Then all regression tests were run. As expected the chgres_cube and grid_gen regression tests failed. The output files did not match the official baseline according to the nccmp utility. However, the differences were due solely to the additional metadata and lat/lon records in the files. All other records were identical, as they should be.

Will merge to the authoritative repository.
