Hi Frank,
if you want to plot contour fields in GEMPAK from observed data you
will have to perform an objective analysis on that data first
(http://www.unidata.ucar.edu/software/gempak/tutorial/barnes.html).
GEMPAK is not capable of plotting contours and vectors from
irregularly spaced data, you have to convert it to a regular grid
first.
I'd say that its easier (and much faster) for a novice user to use the
initialization fields from NAM or GFS, even though the results will be
somewhat different.
Best Regards,

Greetings....
Sorry if this is an easy one, but I am new to this and have not been
able to find info on the gembud email archive. I would like to plot the
500mb height falls (as was standard on the old DIFAX maps). Is there a
way to do this with the observed data, or am I better off using the
initialization fields from the NAM or GFS?
Thanks in advance...
peace,
frank
