CDO

Hi all,

I have a netcdf output of a regional climate model which is performed on a rotated pole grid and has a (0,0) latitude and longitude point in the middle of the region of interest (South America). However, when plotting a variable the map is trying to plot the variable over the west coast of Africa, as this is where (0,0) is in the real world.

I have attempted to convert the data from rotated pole to regular lat/lon by using remapping tools of cdo. This is raw grid information of the netcdf file:

1. gridID 0 #
   gridtype = lonlat
   xname = longitude
   xlongname = longitude
   xunits = degrees_east
   yname = latitude
   ylongname = latitude
   yunits = degrees_north
   xsize = 146
   ysize = 167
   xfirst = 143.92
   xinc = 0.44
   yfirst = -38.28
   yinc = 0.44
   xnpole = -56.06
   ynpole = 70.60

and this is sample grid information on which I am trying to remap by using command "cdo remapbil,samplegrid -setgrid,rawgrid ifile ofile"

1. gridID 0 #
   gridtype = lonlat
   xname = longitude
   xlongname = longitude
   xunits = degrees_east
   yname = latitude
   ylongname = latitude
   yunits = degrees_north
   xsize = 181
   ysize = 155
   xfirst = -106.25
   xinc = 0.5
   yfirst = -58.25
   yinc = 0.5

However, the map is still trying to plot variable over the west coast of Africa. I have also followed other threads such as https://code.zmaw.de/boards/1/topics/2632?r=2634#message-2634 to fix the problem, however no success.

I guess it may be related with lack of polar coordinates in the raw grid files, but I have no idea about the coordinates.

Does anyone could help me how to fix it?

Thanks in advance,

Deniz
