How to regrid CMIP5 ocean wmo data to regular 1X1 grid

Hi,all

 I have downloaded CMIP5 ocean wmo
data (wmo_Omon_CMCC-CM_historical_r1i1p1_187001-187912.nc), but find that
the horizontal grid is not regular grid.

Therefore I think I need to regrid this data from these irregular grid
points to the regular 1X1 grid.

 I am asking if NCL can do the interpolation? If so, Could you point out
to me the key sentences used in NCL scripts?

 Thanks!
