Quick follow-up.there's definitely no bug.  The output files between both
GEMPAK versions are nearly identical.  I was hung up on the fact that the
new version isn't printing "[GDRADR 0]  Using:  ".  I mistakenly took that
to mean that no stations were being used to create the mosaics, which is
incorrect.

Hello gembuds,

 

I noticed a possible strange bug with GDRADR when upgrading to the latest
Jun 6, 2014 version of GEMPAK.   I was able to reproduce the error with both
source gempak-7.1.0.tar.gz and the binary gempak-7.1.0-1.x86_64.rpm.   The
server is running CentOS 6.5 and up to date.

 

Below are three example GAREA / PROJ.  GDRADR seems to be trying to ingest
the same stations even though the AREA / PROJ are different.  Included is
the output from gempak-7.1.0-1 and an older version gempak-7-4 (rpm).

 

Note that the 20140930 are showing up b/c this LDM has been off for a few
days and was just turned on to test this issue.

 

Thanks and have a good weekend everyone,
Evan
