Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.

New GEMPAK Surface Station File for 7.1.0

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
https://github.com/mjames-upc/gempak-stations
The table is created from the NCAR / RAL master file:
https://weather.rap.ucar.edu/surface/stations.txt
The new GEMPAK table is available now at
https://raw.githubusercontent. com/mjames-upc/gempak-stations/master/sfstns.tbl

$GEMTBL/stns/geog.tbl will also be updated to be consistent with the NCAR / RAL file.  The new GEMPAK geog.tbl is available at:
https://raw.githubusercontent. com/Unidata/gempak/master/gempak/tables/stns/geog.tbl

Comments:

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.
