20011116: 6km mosaic GEMPAK files

Patrick,
The composites are best viewed either with NMAP2 as the gui,
or gdplot2 from the command line.
The $GEMTBL/config/datatype.tbl file has aliases for
the national mosaic as NEXR and the regional as NEXL and NEXF
(for a floater and or a local you would create for your own region).
The $GEMTBL/nmap/mod_res.tbl provides for two products:
Radar_Reflectivity and Radar_Reflectivity_qc
You may want to add "nexf" to the "nexr;nexl" list as well.
The difference between the two products above is that
Radar_Reflectivity uses a gdplot2 TYPE=Z and
Radar_Reflectivity_qc uses a gdplot2 TYPE=F.
The former just fills in the grid boxes. The later contours the data
for a slightly smoother appearance.
If you are looking for an example of plotting the data in gdplot2, use the
restore files mentioned in the mod_res.tbl entry as a guide and
consult the GDRADR page for examples of how to
use the grids in precipitation type plots, etc.

look at the section "Using radar data in grid calculations"/
