Dr. Charles K. Gatebe works with the Universities Space Research Association based at NASA Goddard Space Flight Center, Climate and Radiation Laboratory. He’s a group lead and the principal investigator of the CAR instrument. He obtained his Ph.D. degree in atmospheric sciences from the University of Witwatersrand, South Africa in 1999. He has over 15 years experience in airborne measurement and analysis of surface bidirectional reflectance distribution function (BRDF), that are needed to study and advance the knowledge of clouds, aerosols, ecosystem structure and function, albedo, and feedbacks to climate. In addition, he has experience in calibration of scanning radiometers, and has led the development of a new instrument (CANS) and BACAR, which is under development. He has participated in many in field experiments, including SAFARI-2000 (southern Africa, 2000), CLAMS (USA, 2001), INTEX-B (Mexico, 2006), CLASIC (USA, 2006), ARCTAS (Canada, Greenland and USA, 2008) and DISCOVER-AQ (USA, 2014). Gatebe has received many awards: 2013 Robert H. Goddard Award for Outreach "for founding, implementing, and continuing to lead the spectacularly successful "Maniac" series of talks at NASA Goddard" and the World Meteorological Organization Young Scientist Award in 2000. He has also received other honors: in 2007 by NASA GSFC's Climate and Radiation Branch for his outstanding scientific leadership in conducting airborne measurements and NASA's Group Achievements awards in 2008 and 2009 for participating in the INTEX-B and ARCTAS field experiments, respectively.
