GRACE Science Team Meeting, October 23-25 in Austin, TX
Thursday, May 23, 2013

The Dryden G-III is back in service and there are four L-band flights planned for this week, one over the Slumgullion landslide area in Colorado and the other three over the Santa Barbara and Los Angeles Basin area of the San Andreas Fault. The Weather forecast looks good for this week, with no predicted thunderstorms; this should minimize the potential of atmospheric effect distorting small surface deformation signatures in the Repeat Pass Interferometric data products.

The processing team has been busy processing data acquired in South America. Polarimetric data quality has been excellent. Shown below is a polarimetric image of the Uturuncu volcano in Bolivia, the subject of intense international scientific studies. This stratovolcano last erupted more than 300,000 years ago, but the ground surrounding the volcano has been rising 1-2 cm per year since the early 1990s, making it one of the fastest uplifting volcanic areas on the Earth. This volcano will be imaged again next year, and the team will be able to derive the amount of surface deformation from repeat-pass interferometric data products.
