Welcome to the Earthscope SAR Data Archive at UNAVCO.
A goal of EarthScope
is the improved understanding of the tectonic evolution of the North American continent.
Identifying and understanding deformation rates in all tectonic regimes is critical to reaching that goal.
The GeoEarthScope project, a part of the EarthScope Program,
included the acquisition of SAR data, aerial and satellite imagery,
and geochronology data,
to examine the strain field beyond the time scales available from the PBO geodetic instrumentation.
UNAVCO provides support for EarthScope-related data aquisition, archiving, and distribution.

The UNAVCO Earthscope SAR Archive
|
|
As part of Earthscope's GeoEarthscope project, UNAVCO created an archive of SAR imagery, with
data supplied by the European Space Agency (ESA; ERS1, ERS2, and
Envisat missions) and the Alaska Satellite Facility (ERS1, ERS2 and Radarsat 1).
This SAR data will aid research into earth deformation in
North America caused by earthquakes, volcanoes, and other plate tectonic processes.
UNAVCO's main tasks included placing, managing, and tracking data
orders, working with ASF and ESA, and creation and operation of the data archives, web site, and online services.
UNAVCO designed and implemented a database to support archiving and and data search, built the
physical data archive including hardware and selection and purchase of more than 40 terabytes of storage,
implemented data access permission mechanisms, and created online services for users to find and download
data available in the archive.
UNAVCO continues to work with SAR scientists to ensure the best data is archived and available
in the most efficient manner, and to add new services as needed. The online
numerical search tool
and spatial search (SAR Archive Search Interface)
show the archive contents, and provides KML files for display of SAR scenes in Google Earth.
Proposed, submitted, and received data and tasking orders are available on the
data orders page.
Details regarding the scenes in the Basin and Range Cat-1 proposal are available
here.

UNAVCO Earthscope SAR Archive Status
|
As of January 2009, more than 36,000 SAR scenes had been added to this archive, stored in more than 16 terabytes.
See the status page.
| Access to the GeoEarthscope Project SAR Data
|
Institutions with a basic research mission are eligible to apply for access to the GeoEarthscope
project's SAR data.
Access to SAR data files is limited to approved and registered users. To apply for data access, see
Apply for access.
If you use SAR data you will be interested in the
WInSAR Archive at UNAVCO.
And be sure to investigate the Supersites (hosted by UNAVCO).
| Funding for UNAVCO GeoEarthscope operations and
data acqusitions is provided by NSF and NASA. Important assistance has also been provided by the ESA, the USGS, and the ASF. |
