Prepared by the U.S. Air Force Global Weather Central (AFGWC). For
each station listed, there is a name, WMO number, country code,
latitude and longitude, elevation, and codes for observation types.
This list supports many datasets where the observation report shows
only the WMO number as a station identification. Frequently updated
by the USAF, we get some of those irregularly. DSS has built some
subsets, and has been at work compiling an historical library which
documents station period of observation, station moves, etc.
