Research Bio/Interests

Dr. Tselioudis heads a research team that analyzes observations and model simulations to investigate cloud, radiation, and precipitation changes with climate and the resulting radiative feedbacks. Research focuses on understanding the relationships between atmospheric dynamics and cloud changes, examining processes such as midlatitude storm properties and their climate variability, and on applying advanced techniques to derive atmospheric states from cloud property retrievals. Dr. Tselioudis received the American Geophysical Union Charles Falkenberg Award in 2004.
