On August 29, 2000, Kristina Katsaros interviewed Dr. Joost Businger for the American Meteorological Society’s Tape Recorded Interview Project, managed by the National Center for Atmospheric Research (NCAR). Businger, a prominent atmospheric scientist, discusses his early life, career, and contributions to meteorology. Born in Holland, Businger developed an early interest in weather, which was further fueled during World War II when weather information became classified, leading him to keep his own records and make forecasts. He pursued studies in physics and mathematics, with a focus on meteorology at Utrecht University, ultimately leading to his PhD in 1954. In the interview, Businger reflects on his research and academic career, including his move to the United States in 1956, where he joined the University of Wisconsin as a research associate. He worked with Vern Suomi on sonic anemometer data analysis, a pivotal area in atmospheric turbulence research. Businger discusses his transition to the University of Washington, where he continued his boundary layer meteorology work and became a key figure in the department, contributing significantly to field experiments like the Kansas and GATE experiments. His collaborations with international scientists, including his experiences in the Soviet Union during the Cold War, reveal the global nature of meteorological research during this period. The interview also covers Businger’s later years at NCAR, where he continued developing measurement technologies, such as the Atmospheric Surface Turbulent Exchange Research (ASTER) system. He reflects on his retirement and ongoing work, including collaborations with his son, Steven Businger, and their involvement in the development of smart balloons for hurricane boundary layer measurements. Throughout, Businger highlights the importance of fieldwork, mentorship, and international scientific cooperation in advancing meteorological knowledge.
