20020118: Source of AIREP data



Pat,

It looks like the AIREP data on NOAAPORT can be either lat/lon
or waypoints. The UB.. look to be more of the latter.

GEMPAK 5.6 does have a decoder for the AIREP/AMDARs carried on NOAAPORT.
These are the data that Bob Creasy would be obtaining from our IDD.
So, if he can store the in files for you that is what I could give you.

My decoder pattern looks like:
#
# Decoder for Aircraft Observations
DDPLUS|IDS      (^U[ABDR].... ....|^XRXX84 KAWN|^YIXX84 KAWN) 
([0-3][0-9])([0-2][0-9])
        PIPE    decoders/dcacft -e GEMTBL=/home/gempak/NAWIPS/gempak/tables
        -d data/gempak/logs/dcacft.log
        data/gempak/acft/YYYYMMDDHH_acf.gem

The GEMPAK decoder does use a AIREP waypoints translation table as well as a
PIREP navaids table. The waypoints table is:
$GEMTBL/stns/airep_waypnts.tbl

From a bulletin "UBUS1 KNKA 222058" which contains the report:

ADQ UA /OV ADQ-ODK270021/TM 2008/FL130/TP C130/SK OVC001/TOPS130/WX
 FV01 SN/TB NEG/IC NEG=

I get the following decoder output:
