Presented By: Aerospace Engineering
Chair's Distinguished Lecture: Emerging InSAR Applications for Observing the Dynamics of Earth Systems
Ann Chen
Assistant Professor
Dept. of Aerospace Engineering and Engineering Mechanics
The University of Texas at Austin
Over the past 60 years, advances in satellite remote sensing techniques have made it possible to observe the Earth with finer resolution and broader coverage than could ever be achieved before. In particular, Earth-observing radar satellite missions have generated a large volume of Interferometric Synthetic Aperture Radar (InSAR) data since 1992 with 10s-100s of meters spatial resolution. Recently launched Sentinel-1 mission has provided global coverage and open data access on a 6-day repeat cycle (with a two-satellite constellation). The upcoming NASA-ISRO Synthetic Aperture Radar (NISAR) mission is scheduled to launch in 2023, which will continue to provide high-quality radar data free of charge for scientific uses in the coming decades. In this talk, we will discuss how to infer a broader range of properties of the earth’s surface and subsurface using InSAR. These newly available satellite observations have opened up new research opportunities in understanding the dynamics of earth systems.
About the speaker...
Ann Chen received a B.S. degree in geophysics from the University of Science and Technology of China in 2008; an M.S. degree in electrical engineering in 2012 and a Ph.D. degree in geophysics in 2014 from Stanford University, California. She has more than 10 years of experience in SAR/InSAR algorithm design for earth system science applications. In 2017, she joined the Department of Aerospace Engineering and Engineering Mechanics at The University of Texas at Austin as an assistant professor. Since 2018, she has also served as a faculty member (by courtesy) in the Department of Geological Sciences at UT Austin. She currently leads the Radar Interferometry Group housed in the Center for Space Research. Her group focuses on the development of new satellite, and especially interferometric Synthetic Aperture Radar (InSAR) techniques, for studying natural and induced seismicity, groundwater resources, natural disasters, and permafrost hydrology and carbon storage.
