Hi Don, The use of "grid_latitude" and "grid_longitude" standard names indicates a rotated pole grid mapping (defined in Appendix F: "Grid Mappings" section  of the CF spec). But lat and lon have the wrong units for a rotated pole grid (they should be "degrees") and a rotated pole grid mapping is not defined. (Here's the definition for "grid_latitude"  from the CF standard name table .) Was the original dataset on a rotated pole grid? Ethan  http://cfconventions.org/1.6.html#appendix-grid-mappings  "Latitude is positive northward; its units of degree_north (or equivalent) indicate this explicitly. In a latitude-longitude system defined with respect to a rotated North Pole, the standard name of grid_latitude should be used instead of latitude. Grid latitude is positive in the grid-northward direction, but its units should be plain degree."  https://badc.nerc.ac.uk/help/formats/netcdf/cf-standard-name-table.html Don Murray wrote: > It doesn't like the standard_name for latitude and longitude (using ncml > to remove them makes the grid readable).
