InSAR (Interferometric Synthetic Aperture Radar) is a powerful tool for measuring Earth surface deformation due to earthquakes, volcanic unrest, ground water migration, and anthropogenic activity. Terabytes of InSAR data were collected for the EarthScope program that spans the entire US. Training new scientists for the interpretation of these important data sets is critical to the EarthScope mission. InSAR is also being increasingly used in studies of cryosphere (motion of glaciers and ice sheets) and atmosphere (water content in the troposphere). This short course will also help prepare scientists for the upcoming NASA InSAR mission, now called DESDynI (Deformation, Ecosystem Structure and Dynamics of Ice).

New techniques and applications of InSAR are rapidly developing, including stacking, time-series analysis of surface deformation, ScanSAR, polarimetric InSAR, and along-track interferometry. A 2.5 day workshop will introduce InSAR processing and applications to new users.

If you have considered using InSAR data and imagery in your research or want to learn more about how to apply InSAR to new areas of research, this workshop is for you. The workshop includes an overview of the technology and its application to Earth Science, an introduction to a common processing package, and an overview of different processing packages. In a hands-on session (“tinker time”), the students will use the InSAR software to process example data. An additional optional module on Wednesday afternoon will cover subpixel ground motions from glaciers, landslides, earthquakes, etc. measured from pairs of optical and SAR images using a technique called pixel or feature tracking.

Faculty: Paul Rosen, JPL; Eric Fielding, JPL; and Matthew Pritchard, Cornell University

These courses do not have a registration fee, but participants will pay their own travel and living expenses. UNAVCO will provide lunch and snacks during the short course. Scholarships are available for students who will utilize this information in their current research.
