Hi all,
I'm attempting to compute the difference of a scalar variable
between two forecast times, with the grid information located
in two *different files*, using gddiag.
So, I have data for forecast hour 000 in file one, and data
for forecast hour 003 in file two. Attempting to do something
like
gdfile = filef000.gempak + filef003.gempak
gfunc = sub(scalar,scalar+2)
yields a "Cannot find scalar^f000" error when ran. Can gddiag
compute data from files that contain different dates/times? Or
does all the data have to be in one file?
Thanks for any information or help.
Jason
