CDO

Dear All I have a model output which is in rotated grid have a look at below:

*[pmdtest@pmd output]$ cdo sinfov tas_WAS-44_ECMWF-ERAINT_evaluation_r1i1p1_SMHI-RCA4_v1_mon_200001-200012.nc
File format: netCDF
-1 : Institut Source Name Time Typ Grid Size Num Levels Num
1 : unknown unknown var250 var F32 24948 1 1 1
Horizontal grids :
1 : lonlat > size : dim = 24948 nlon = 198 nlat = 126
rlon : first = -31.68 last = 55 inc = 0.44 degrees
rlat : first = -21.12 last = 33.88 inc = 0.44 degrees
northpole : lon = -123.34 lat = 79.95 *

Refering to some previous posts I made the weights file of this data file and then removed xnpole and ynpole from the griddes and regrided it. Now the file is on lat lan grid as you can see below but the map is still wrong when I display with Grads.
