Seung-Hee Ham

About

Dr. Seung-Hee Ham received her bachelor’s degree in atmospheric science in 2004 and a Ph. D. degree in satellite meteorology in 2010 at Seoul National University, South Korea. Then she moved to the US in 2011 to start her NASA postdoctoral program to research about the three-dimensional radiative transfer modeling in cloudy atmospheres to support the CERES Surface and Atmospheric Radiation Budget (SARB) project. After finishing the postdoctoral program, she worked as a NASA contractor about 10 years and joined a federal service in 2024. Her expertise is analysis of cloud and radiation satellite products, merging cloud properties from multi-sensor satellite products, radiative transfer modeling, and derivation of simplified radiative equations.
