David Atlas is one of the most influential people in the past 60 years in the field of radar meteorology. His basic research, which began shortly after WWII, laid the foundations for the quantification and interpretation of weather radar echoes. Dr. Atlas’s many patents have led to the development of practical airborne radars for severe weather avoidance on commercial aircraft. He also established world-class research and development (R&D) groups at Air Force Cambridge Research Laboratories, the University of Chicago, the National Center for Atmospheric Research (NCAR), and the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center. Many of his students and colleagues are leaders in the field today.
