Ali Behrangi

Associate Professor, Department of Hydrology and Atmospheric Sciences.

Dr. Ali Behrangi has more than a decade of experience in various aspects of cloud and precipitation studies. He has been involved in development and analysis of satellite-based high-resolution multi-sensor precipitation estimation algorithms, diagnostic evaluation and uncertainty analysis of precipitation products (IR, microwave, radar), extreme weather event analysis, and hydrologic modeling and application. In the last 6 years, he has had a greater focus on remote sensing of precipitation in cold regions, where he has also utilized CloudSat, GRACE, reanalyses, and other new observations. He is a member of the NASA Energy and Water Cycle Study (NEWS), GRACE science teams, the International Precipitation Working Group (IPWG), and WCRP/GEWEX panel on weather and climate extremes. He also leads an effort under NASA MEaSUREs to advance GPCP precipitation data record in high latitudes. He was a research scientist at NASA JPL for more than 5 years (2012-2017), and recently moved to University of Arizona.
