Matt,

The compile time defaults for the GEMPAK distribution are for
array sizes to accomodate 300 times in a data file for plotting
(eg 150 days of 0Z and 12Z observations).

If you needed more than 300 times in a plot, you would have to 
increase the LLMXTM  and LLTMCX parameters in:
$GEMPAK/include/GEMPRM.PRM
$GEMPAK/include/gemprm.h
(currently both values are 300)

and

change the MMHDRS values in the above file to be
MMHDRS = LLMXTM + LLSTFL 
currently these values are:
MMHDRS = 30000
LLMXTM = 300
LLSTFL = 29700

You would need to build the distribution from the source
tar file available on our download site.
