GEMPAK Users,
I've provided a patch for GEMPAK 5.11.4 which improves the handling of
new high-res level 3 NEXRAD products (N0Q, N0U and others). The updates
provide support for higher resolution color tables (lutfils).

<http://www.unidata.ucar.edu/staff/mjames/gempak/gempak_upc5.11.4-upd-201004.tar.gz>
The patch includes:
* fully updated gemlib/im library
* three new higher-res color tables
1) upc_n0q256.tbl - full spectrum color table equivalent to previous
16-color table (capped at approx. 75 dBZ)
2) nids_n0q256.tbl - non-operational proposed next generation radar
color table (see: http://radar.srh.noaa.gov/ )
3) upc_ref256.tbl - full spectrum color table extending to approx. 94
dBZ)
* gempak/tables/sat/imgtype.tbl - uses upc_n0q256.tbl as default for 256-level
N0Q
* updated ldm/etc/templates/pqact.gempak_nexrad - please see May 17 message
"impending change in IDD NEXRAD3 datastream":
"As a by-product of the ingest code update, the NEXRAD Level III and
TDWR
Digital Precipitation Array (DPA) products (SDUS8) are being moved
from distribution in HDS to NEXRAD3. If you are currently processing
the DPA products, you will need to make a change in LDM pattern-action
file processing. You should implement this change_before_ 15Z on
Wednesday, May 19!"
These updates are also included in the full source available at
http://www.unidata.ucar.edu/downloads/gempak/index.jsp
INSTRUCTIONS:
* save to $NAWIPS
* uncompress (tar -xvzf gempak_upc5.11.4-upd-201005.tar.gz) in $NAWIPS (this
will overwrite imgtype.tbl,
upc_ref256.tbl and the full gemlib/im directory)
* cd $NAWIPS/gempak/source/gemlib/im/
* make all
* ar -rv $OS_LIB/gemlib.a *.o
* cd $NAWIPS/gempak/source/programs/
* make clean all install
Compilation problems and other questions should be sent
