Hi-
I have some climate files that have a rotated-pole projection defined as:
char rotated_pole ;
rotated_pole:grid_mapping_name =
"rotated_latitude_longitude" ;
rotated_pole:grid_north_pole_latitude = 90.f ;
rotated_pole:grid_north_pole_longitude = 0.f ;
When I read this through the netCDF-Java library, the data end up 180
degrees off from where it is supposed to be (African data is over
Hawaii). I talked to John Caron at Unidata and he doesn't know if it is
a problem with the grid definition or the rotated-pole code in netCDF-Java.
Does anyone on this list have a pointer to the equations for the rotated
pole and or know if there anything wrong with the grid mapping
definition? Should the above imply a unity transformation?
Sample files are at:

thanks for the help!
