CF folks, Many ocean models have curvilinear grids, but most of the ones I've encountered have 2D coordinate variables lon,lat that are monotonic and have no missing_values.
The NOAA forecast model for the St. Johns River Operational Forecast System, however, has a complex geometry, and used a grid generator that allowed for "cuts" in the grid, so that in the resulting grid system lthe coordinate variables on/lat are not monotonic and have missing values. I did an experiment to see if I could fill in the missing lon/lat values via interpolation, but this exercise only made it clear that this cannot work, as the data being interpolated are not monotonic. Check out the first figure here to see the issue: https://www.wakari.io/sharing/bundle/rsignell/SJROFS Is there any way this operational forecast data could be made to be CF compliant?
