[ncl-talk] ESMF in NCL

[Mary Haley]

Jeff,

I won't get to this before I leave for the day, but to save time, I would
think that inside the "do m=0,11" loop, you could set the last argument of
resize_grid to True for the first iteration, and then to False for the
other 11 iterations.

This will probably not fix the original problem, but I wanted to point it
out for future use.
