GIST Station Information
     
     1.0  General Description
     
          The GEWEX Continental-Scale International Project (GCIP)
     Integrated Systems Test (GIST) datasets contain data collected from
     approximately 4000 stations in the GIST domain (i.e., approximately 91W
     to 107W longitude and 31N to 40N latitude) for the period 01 April 1994
     through 31 August 1994.  The station information provided defines each
     station in the GIST dataset with station location, name, frequency of
     observation, etc.  For a complete description of the station information
     file format, refer to section 2.1.

     2.1  Detailed Format Description
     
          The following is a complete description of the station information
     provided with the GIST data.  Table 1 details the station list parameters.
     The beginning and ending dates for the period of coverage are either in
     Universal Time Coordinated (UTC) or local time and is network
     dependent. The Identification Type field is network dependent, and
     indicates the source of the Identification field.  Example Identification
     Types are WBAN, FAA, etc. The Occurrence field is an integer value used
     to indicate co-located stations. Note that when a particular parameter is
     unknown for a station, either a blank  or a question mark will appear in
     that parameter's position.  For a complete list of Country, State, and
     County values, refer to the documents in the reference section below.  
     Possible platform types and frequency values are listed in tables 2 and 3,
     respectively.  Note that only those platform types present in the GIST data
     have been listed.
