How to convert variables to (lat, lon) by cdo？

Hi everyone,
I am trying to use CDO convert variables to (lat, lon). I perform the following,but I can't come up with the 3D variable.

I use the cdo commond:cdo -setgrid,grid.nc pr.nc temp0.nc

The grid.nc is

The result of the processing is still exactly the same as the information in the original file (the file information )

Do you know how to convert pr(time, ncells) to pr(time, lat,lon) using the CDO command?
Thank you in advance
Rilia

Hi Jinyan,

both files have unstructured coordinates. If you have global data you can remap it to a regular lonlat grid, e.g. global 1x1 degree

cdo -remapnn,global_1 infile outfile

There are many examples how to do it in the support or open discussion forum. See also the FAQ how to use a grid description file https://code.mpimet.mpg.de/projects/cdo/wiki/FAQ
