GCIP LSA-NW EAOP 1999 Station Information
     
     1.0  General Description
     
          The GEWEX Continental-Scale International Project (GCIP)
     Large Scale Area-Northwest (LSA-NW) Enhanced Annual Observing Period (EAOP)
     1999 datasets contain data collected from over ten thousand stations
     in the GCIP LSA-NW EAOP 1999 domain (i.e., 36N to 51N latitude and 
     90W to 115W longitude) for the period 01 April 1999 through 
     31 March 2000.  The station information provided defines each 
     station in the GCIP LSA-NW EAOP 1999 datasets 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 GCIP LSA-NW EAOP 1999 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, a 
     question mark, or all 9's will appear in that parameter's position. For
     a complete list of Country, State, and County values, refer to the
     documents in the references (Section 4.0). Possible platform types and 
     frequency values are listed in Tables 2 and 3, respectively.  Note that
     only those platform types present in the GCIP LSA-NW EAOP 1999 data have
     been listed. Table 4 lists commissioning dates for all stations 
     commissioned (where applicable) during this project.
