Research Interests: 

Dr. Jeffrey Basara is a member of the OK NSF EPSCoR Track-1 RII Award titled Socially Sustainable Solutions for Water, Carbon, and Infrastructure Resilience in Oklahoma. The $20 million research project is a social science-led, multi-disciplinary collaboration among social, physical, biological, engineering, and computational scientists. More than thirty researchers from across the state are working together on the project, which began July 1, 2020.

Dr. Basara is an associate professor of meteorology and associate professor of civil engineering and environmental science at the University of Oklahoma. He is director of the Kessler Atmospheric Ecological Field Station and executive associate director of the Hydrology and Water Security program.

Dr. Basara's research interests focus on the integration of our understanding across weather, climate, water, and ecosystems. His research activities include land-atmosphere interactions, drought, flash floods, urban meteorology, severe weather, instrumentation, and severe winter weather. His research also pursues the validation of remotely sensed soil moisture and skin temperature from satellite-mounted instruments, as well as the development, validation, and improvement of land surface models used in numerical weather prediction.

Dr. Basara serves as Team Lead of the OK NSF EPSCoR project's Focus Area 1: Changing Subseasonal to Seasonal (S2S) Weather Patterns. Change in both natural and human systems in Oklahoma is being driven by rapidly changing patterns of subseasonal to seasonal weather. These fluctuations include shifts in average and extreme precipitation and temperature on scales of 10-90 days. Changes are occurring in the context of competing social narratives of human activities' effect on climate, complicating recognition of and response to changing S2S patterns. Through his work with the S2S team, Dr. Basara will seek to (a) better understand the basic processes driving changes in S2S patterns, (b) improve models and predictions of basic S2S process and events; and (c) develop data necessary for managing water, carbon and water cycles, and infrastructure in Oklahoma.

Dr. Basara also serves as the director of the Kessler Atmospheric and Ecological Field Station, where he works closely with scientists across multiple disciplines to increase the overall understanding of the complex interactions within the environmental column. Additionally, he is the executive associate director of the Hydrology and Water Security Program at the University of Oklahoma and leads the CHEWe Research Group.
