[gradsusr] gribmap not working with grib2 ice

[Wesley Ebisuzaki]

Jennifer,

PDS Template 4.15 was designed for regridding a field.  For example, you 
have
a high-resolution field that you want to send to the field as a 
low-resolution grid.
A pilot may want to know the average and peak winds in his 1x1 degree box
for flight planning.  That would more practical than giving, for 
example, a 8 km grid.
All template 4.15 tells you that the grid was converted into a new grid 
and how
the conversion was done.
