As Dennis already mentioned there are a few other examples for
regridding a curvilinear grid to latlon grid. See examples 30 and
32.<br>

<div>Thanks Karin,</div>
<div>With your help to use the "function" ESMF_regrid, I had
regrided my data. (I only changed example's DstGridType to
"0.45deg", DstLLCorner to (/30.d, 120.d /) and DstURCorner to
(/66.d, 156.d /) ) But I found that the plot outcoming is quite
different, the value at the same point is unmatched. My former
grid interval is about 0.44 degree, I changed to regrid to 0.5
or other degree, they all failed all the same. The output pic's
link is here <a

that mean the data is unsuitable to regrid in this way?</div>
<div>Really looking forward to your advice.</div>
<div>Sincerely,</div>

Hi Yan,<br>
if you have lat(y,x) and lon(y,x), which is a curvilinear
grid, you can <br>
use ESMF to regrid it to a regular latlon grid.<br>
Have a look at ESMF example 7 <br>
