Subject: USGS Data Access
 
As of today, the data from USGS stations in the SCIGN
network's Dense GPS Geodetic Array in the Los Angeles
region will be downloaded by the USGS in Pasadena.
Prior to today, these stations were downloaded by
Scripps.  This change was made possible by their
development of highly automated downloading routines
that are very useful for our Ashtech equipment.
 
In particular, Burc Oral, Y. Bock and J. Behr have
made available the beta version of DASS (release 1.0)
for use in the Pasadena Field Office.  The Scripps
group has been extensively testing DASS, and it was
readily installed and adapted to the particulars of
our computing environment here.
 
Downloaded files are sent both to the Scripps Orbit and
Permanent Array Center (SOPAC) and to a UNIX machine (ss10)
here at the USGS in Pasadena, called tango.gps.caltech.edu
(131.215.66.161).  The machine here, tango, will serve as
a short-term data holding area.  RINEX files will be kept
on-line on tango for up to a few weeks.  But we will be
relying on other archive facilities (SOPAC, others) to maintain
and archive these data for the long term.
 
Please report any problems with the data or tango's anon ftp
site to me - I hope that this change is not too disrupting
to people's existing procedures for accessing the data
from the USGS stations.
 
The stations that the USGS will now download from the
Pasadena office are: CHIL, CLAR, CMP9, HOLC, HOLP, LEEP,
LONG, ROCK, DAM1, and BRAN.  We anticipate adding DAM2
to our downloading list once it is operational (probably
in early September).  Same for the new site at Table
Mountain, TABL, once it is operational (approx. late
September).
