The upcoming release of GEMPAK 7.1.0 will include a new
global surface METAR table (sfstns.tbl), created by a new
Python decoder available at
http://github.com/mjames-upc/gempak-stations
The table is created from the
NCAR / RAL master file:
http://weather.rap.ucar.edu/surface/stations.txt
The new GEMPAK table
is available now at

$GEMTBL/stns/geog.tbl will also be updated to be consistent
with the NCAR / RAL file. The new GEMPAK geog.tbl is
available at:
http://raw.githubusercontent.
com/Unidata/gempak/master/gempak/tables/stns/geog.tbl
The stations.txt from AWC is more up-to-date as it has updates from April 2014.

Andrew, you're right the AWC file has been updated more recently, but it contains approx. 270 less entries than the file at weather.rap.ucar.edu. Regardless of which one you prefer, the python decoder ( https://github.com/mjames-upc/gempak-stations/blob/master/stations.py ) will work the same on both files.
