Ph.D. student Xuechen Yang was featured in a recent Ohio State News story for her work on “Satellite Altimetry Applications on Land Subsidence,” which she presented last month at the American Geophysical Union Fall Meeting in Chicago. This research uses satellite radar altimetry to monitor land subsidence over Central Valley, California. Data from multiple satellite altimetry missions are processed to generate an 18-year, 2003–2021, land deformation time series over the large subsidence bowl near the city of Corcoran, CA. The study concluded that satellite altimetry could be an effective tool to monitor land subsidence and compliments other satellite geodetic techniques, as well as in-situ land subsidence measurements. This research is supported by NASA, a fellowship awarded by Topcon Positioning, LLC, and the Friends of Orton Hall.
