First obvious thing I've found is that you are rereading all of
those 3-D fields from the file at every level, resulting in 7x the
I/O. All of those reads should be moved outside of the inner loop so
you only read the data once and subset as needed.<br>

<div>I'm running this script (attached) twice daily to grab NAM
forecast model data and plot results. It plots data at each
hour and several pressure levels for two regional domains over
the U.S. The program works great, though it takes 200 minutes
to finish, and I'm wondering what I may be doing that is
redundant that is slowing it down? I tried to eliminate some
things but it didn't seem to help. Are there any suggestions
for how to make this code more efficient?</div>
