He served as associate director and senior scientist at the National Center for Atmospheric Research (NCAR).
[1] His graduate studies at U.C., Berkeley were interrupted by World War II, when he served in the Air Force's new meteorological program.
After the war, while working on a PhD from UCLA, he joined the RAND Corporation in Santa Monica, California, where he was instrumental in establishing the potential value of satellites in meteorological research.
His 1951 research paper (written with S. M. Greenfield)[2] introduced many of the concepts still in use today, including the effects of Earth's oblate shape, which is now exploited to produce solar synchronous satellites for weather observation and other forms of remote sensing.
This resulted in the first unclassified report in a scientific journal describing such fallout and his testimony on this subject before a joint committee of Congress.
