Synopsis
grd2kml.csh grd_file_stem cptfile [-R<west>/<east>/<south>/<north>]

The name (without file extension) of your grd file (must be in geocoded (lat/lon) coordinates)
cptfile
Color palette file (can be created using GMT tool makecpt, see usage here: https://docs.generic-mapping-tools.org/dev/makecpt.html )
Optional Argument
-R<west>/<east>/<south>/<north>
Range if you wish to output only a subarea of your grid file
