CDO

I have a CORDEX CAM-44 data in rotated coordinates, but I need the file in non-rotated lat/long. By using cdo sinfo pr_rcp26_2021_2025.nc, I can see both, the rotated and the non-rotated coordinate variable values.

But, with ncdump -h pr_rcp26_2021_2025.nc, the precipitation variable is refered to the rotated coordinates (rlat,rlon). My question is, how can I refer the precipitation data to the non-rotated coordinates? Thanks in advance
