NAME
     gps, bard - description of GPS data at the Northern Califor-
     nia Earthquake Data Center (NCEDC)


DESCRIPTION
     The NCEDC archives and distributes the following GPS data:

     1.   BARD (Bay Area Regional Deformation)  Network  data,  a
          collection  of  continuously  recorded GPS sites in the
          Bay arean and Northern California.

     BARD Network

     The BARD GPS Network consists of continuous GPS sites  main-
     tained  by  UC Berkeley Seismological Laboratory, USGS Menlo
     Park, and Trimble.   The  UC  Berkeley  and  USGS  data  are
     archived  in  both  raw (binary) and RINEX formats, and data
     from the Trimble sites are available in RINEX  format  only.
     Users  are  strongly encouraged to use the RINEX data, since
     the raw data may not always be available online.

     The Data Center does not provide any software for  the  pro-
     cessing  of GPS data.  It is assumed that users of this data
     provide their own processing programs.

     DATA  RETRIEVAL  The  GPS  data  is  available  either   via
     anonymous ftp in the following directories:

     quake.geo.berkeley.edu:/pub/gps/rinex (RINEX data)
     quake.geo.berkeley.edu:/pub/gps/raw (Raw data)
     quake.geo.berkeley.edu:/pub/gps/sites (Site descriptions)

     or from accounts on the data in the following directories:

     /data/dc1/gps/rinex (RINEX data)
     /data/dc1/gps/raw (Raw data)
     /data/dc1/gps/sites (Site descriptions)
