[ncl-talk] regrid

Hi Fiona,
Yes, assuming you can create x/y arrays that houses the new 100km grid.
There are numerous examples on the ESMF examples page of ESMF_regrid being
used to interpolate from a XXkm grid to other grids, but there do not seem
to be any that show the opposite. Regardless, this can be done. Take a look
at example #20 for an idea of how to do it:

<https://www.ncl.ucar.edu/Applications/ESMF.shtml#ex20>
Looking at the script, you will need to provide the lat_dst/lon_dst arrays
to ESMF_regrid.

I do not have any experience doing this type of interpolation; if you run
into issues please respond to ncl-talk as others will likely have to assist.
Adam
