Khosro Ghobadi-Far

Khosro is a fellow of CIRES (Cooperative Institute for Research in Environmental Sciences) and as assistant professor at the Smead Department of Aerospace Engineering Sciences of University of Colorado Boulder. His research deals with quantifying the compounding impact of extreme climate events like droughts as well as humans on freshwater resources such as groundwater using space geodesy techniques of GRACE/GRACE Follow-On, GNSS, and InSAR. He is also interested in exploiting the gravity measurements from GRACE and GRACE Follow-On satellites for new applications such as tsunami observation.

The Gravity Recovery and Climate Experiment (GRACE) satellite mission (2002-2017) consisted of two satellites at ~500 km altitude separated by 200 km, following each other in the same orbit. The distance between the two GRACE satellites changes because of the gravitational pull of the masses beneath the satellites. As such, mass changes at or near the Earth’s surface caused variations in the dista ...[Read More]
