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:

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

If rectilinear and you are interpolation precipitation
and/or flux quantities, you may want areal conserving

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

etc, etc, etc

Send more information to ncl-talk
