Charles Ichoku was hired as a Research Physical Scientist with the Climate & Radiation Branch on August 31, 2008. Dr. Ichoku's research is focused on the global occurrence, distribution, radiative properties, and climate forcing effects of aerosols. He also devotes a large amount of time and effort to the study of fires and their emissions, which include radiative energy and smoke aerosol. His work is a part of the national effort aimed at reducing the currently acknowledged large uncertainties in the knowledge of the aerosol contribution to global climate forcing reported by the Intergovernmental Panel on Climate Change (IPCC).

Dr. Ichoku has been affiliated with the Branch, working with SSAI and the University of Maryland, College Park, since 1998.
