On September 5, ESSIC/CISESS scientist Veljko Petković presented the second seminar of the season at the Department of Atmospheric and Oceanic Science, a talk entitled “Emulating Passive Microwave Satellite Products: Information Content and Uncertainties”.
During the talk, Petković talked about using existing available spatiotemporally continuous satellite products to replicate the information typically offered by sparse low-earth-orbit passive microwave sensor observations. Specifically, he described how GOES-R Advanced Baseline Imager infrared bands could be used to predict otherwise unavailable passive microwave brightness temperatures over oceans at frequencies and accuracies suitable for operational use in precipitation-related applications. The talk was well-attended by graduate students and faculty.
Petković is an Associate Research Scientist at ESSIC. He joined the university in 2017 after graduating at the Department of Atmospheric Science at Colorado State University. His research interests are in hydrology, atmospheric radiative transfer, and microwave remote sensing, with focus on satellite retrievals, cloud microphysical processes and their interactions with a large-scale environment.
