The SFPARM definition you will want to use if "sgnl", with an optional marker
design appended (SFPARM = sgnl;mark:1.1.1)
Here's an example of what I use for SFMAP
AREA = dset
GAREA = usnps
SFPARM = sgnl;mark:1:1:1
DATTIM = first
SFFILE = nldn
COLORS = 0;30
MAP = 6
MSCALE = 0
CLEAR = y
DEVICE = XW
PROJ = str/90;-100;0
I start with DATTIM = first for SFFILE = nldn (which points to
$GEMDATA/nldn/20121025HHMM.gem) because the file may not have data for the last
5-minute period in the 30-minute file (where DATTIM=last would equate to 1855
UTC if the 1830 UTC file is being read before 1855 UTC). This can all be
checked for in a shell script with the program "sfctime", which will report the
available times in a GEMPAK surface file:
> sfctime nldn
121025/1830
121025/1835
121025/1840
121025/1845
Hopefully this will help set you right on displaying NLDN data.
Best,
Michael James
