The problem is that the file has
double lat(lat=94);
:standard_name = "grid_latitude";
:long_name = "Latitude";
:units = "degrees_north";
:axis = "Y";
double lon(lon=192);
:standard_name = "grid_longitude";
:long_name = "Longitude";
:units = "degrees_east";
:axis = "X";
But standard_name "grid_latitude"; and "grid_longitude" is used for rotated lat
lon, see:
http://cfconventions.org/standard-names-26.html
the CDM is interpreted this as "rotated lat lon" projection, but fails because
it needs a grid_mapping.
so
1) is this latlon or rotated lat/lon".
2) did original file have these standard_names or did CDO add them?
