Re: what is the most simple way to do regridding?

It is a matter of preference CDO or NCL.

NCL's regridding functions are listed at:
http://www.ncl.ucar.edu/Document/Functions/regrid.shtml

You have not provided much information.
Your grids look essentially the same:
(192,144) and (192,145).
What is the difference?
Are these rectilinear grids or curvilinear grids?
Are they global or regional grids?

If (say) rectilinear then simple bilinear interpolation
may be adequate
   http://www.ncl.ucar.edu/Document/Functions/Contributed/linint2_Wrap.shtml

If rectilinear and you are interpolation precipitation
and/or flux quantities, you may want areal conserving
interpolation
 
http://www.ncl.ucar.edu/Document/Functions/Contributed/area_conserve_remap_Wrap.shtml

All global grids could be interpolated via spherical harmonics
which have the capability of smoothing.

etc, etc, etc

Send more information to ncl-talk

Cheers
