[IGSMAIL-6693] JPL/SOPAC 1994-present timeseries archived at CDDIS

[Angelyn W. Moore]

The JPL Geodynamics and Space Geodesy group and the Scripps Orbit and 
Permanent Array Center (SOPAC) have been jointly supported by NASA for 
the past 10 years to produce and disseminate high-level GPS data 
products, such as time series for North America, through REASoN and 
MEaSURES projects that support NASA's Earth Surface and Interiors (ESI) 
focus area, and that are part of NASA's contribution to the EarthScope 
Plate Boundary Observatory (PBO).

JPL has recently completed a uniform reprocessing made possible by the 
IGS08 GIPSY orbit dataset [Desai et al, 2011].  In turn, this enabled 
extension of the combined SOPAC/JPL timeseries back to 1994-01-01.

We are pleased to announce that the 1994-present combined dataset is now 
available via CDDIS.  Versions with outlier removal, filtering, and 
detrending are available.  As always, these products are also available 
via the GPS Explorer portal, which also provides advanced plotting and 
analysis tools, and by FTP from SOPAC.  Please contact us with any 
questions or suggestions.
