Background
Dr. Charles K. Gatebe is currently an atmospheric scientist in the Goddard Earth Science and Technology Center, University of Maryland Baltimore County. He also holds the position of Lecturer in the Institute of Nuclear Science, University of Nairobi, where he teaches courses on air pollution using nuclear related techniques, but is on leave from his faculty position. He came to NASA Goddard Space Flight Center in 1999 as a Resident Research Associate of the Universities Space Research Association (USRA).
His research experience includes developing a simple gaussian model to estimate motor vehicle emissions from line sources (highways) in Nairobi, in situ measurements of aerosols and gases, and characterizing aerosol sources using measurements at a high mountain (>4200 m above mean sea level) and statistical and trajectory methods. He has been involved in International Atomic Energy Agency (IAEA) coordinated research project on air pollution using nuclear related analytic techniques and in 1994/95 was a member of the United Nations Environmental Programme (UNEP)/World Health Organization (WHO), Global Environmental Monitoring System (GEMS)/Air team of experts.
Dr. Gatebe has been involved with modification of NASA\'s Cloud Absorption Radiometer to have modern data acquisition system and UV optical channels suitable for remote sensing of aerosol. He has participated in several field campaigns and most recently participated in the SAFARI-2000 field experiment in southern Africa, which took place from August-September, 2000 and also CLAMS 2001, USA eastern coast, July-August 2001. In both experiments he made measurements using NASA\'s Cloud Absorption Radiometer aboard the University of Washington Plane, CV-580. Currently, he is interested in remote sensing of aerosols and bidirectional reflectance distributions functions to better understand their role in global change.
Dr Gatebe was recognized for his work as a fellow of Global Change System for Analysis, Research and Training (START) during the 5th International Geosphere Biosphere Programme (IGBP)-Scientific Advisory Committee meeting in Nairobi, Kenya, 1998, and is the winner of the 2000 World Meteorological Organization Young Scientist Award
