List:

Has anyone ever tried plotting the isallobaric wind (vectors or magnitude)
using NARR data? I've tried multiple possibilities using GDPLOT2, but it
doesn't seems to recognize the assigned time range across two separate
files (F000 from files spaced 3-hrs apart). Presumably it's just a syntax
problem...any ideas?

 GDFILE   =
narr-a_221_20030212_0000_000.gem+narr-a_221_20030212_0300_000.gem
 GDATTIM  = 0000F000!0300F000
 GLEVEL   = 925!925
 GVCORD   = PRES!PRES
 PANEL    = 0
 SKIP     = 0
 SCALE    = 0!0!0!0
#GDPFUN   = knts(mag(ISAL))
GDPFUN   = knts(mag(ISAL(HGHT^030212/0000F000+2,HGHT^030212/0300F000+1))
<etc>
