He was also a principal investigator at the Valley Forge Research Center from 1967, conducting experiments measuring the forward scattering and backscattering of electromagnetic waves in the cloudless troposphere.

There he directed the Doppler weather radar project from 1971 to 1987 which led to the development of the NEXRAD network, covering the entire United States since 1990, and which is an essential tool for detection of dangerous meteorological phenomena.

This technology, added during the 2010s to NEXRAD, provides National Weather Service forecasters with a measurement of the size and shape of targets like hail.

[2] He never retired but continued to write articles, to speak at conferences around the world, and advise generations of meteorologists at the University of Oklahoma.

[4] He has published, as author or co-author, numerous scientific articles in more than 20 journals covering his interests in the fields of geosciences, engineering, physics, and meteorology.
