<span style="font-family:Arial;"><span style="font-size:16px;">I cannot do ESMF regridding as per it is not allowed to use the all three dimensions (time, lat, lon). I am little confused here, How can I use ESMF regridding and keep the time dimension also. If so, after regridding, I can perform the ttest for the resolution difference.</span></span>
