Weather Radar Dual Polarization
Penn State’s Ionosphere
Research Laboratory

Thomas A. Seliga is a Consulting Electrical/Electronics Engineer and Atmospheric Scientist, specializing in related areas of remote sensing and systems, aviation systems, surface transportation systems and ionospheric wave propagation.Prior to retiring in 2010, he served as an electronics engineer with the Communications, Navigation and Surveillance Division of the USDOT Volpe National Transportation Systems Center, Cambridge, MA, with involvement of studies and support of operational weather sensors and systems for the Federal Aviation Administration as well as contributions to airport surveillance systems.

Most of Tomís career was spent in academe with a variety of positions at Penn State University, Ohio State University, The University of Washington and the University of Toledo as well as Program Director for Aeronomy at NSF and short-term positions at The National Center for Atmospheric Research, the National Weather Service and the Italian National Research Councilís Institute of Atmospheric Sciences and Climate. His research and teaching interest cover a wide range of topics, incorporating subjects related to electromagnetic wave propagation and scattering in ionized and non-ionized media, atmospheric studies on air pollution, surface surveillance radar techniques for aviation, and airport weather sensors and systems.

The Russian Radiophysical Research Institute has credited Tom with recognizing the possibility of creating artificial periodic inhomogeneities of the ionospheric plasma that helped lead to a new method of experimentation now performed in ionospheric heating facilities throughout the world.

He was the main force in developing the dual polarization concepts that have revolutionized the field of radar meteorology. Recently his investigation have turned to weather-related issues.

Arthur Henry Waynick

Dr. Waynick profoundly influenced the course of radio science and atmospheric research, both in the United States and abroad. His interest in these fields was established during a period of study at the Cavendish Laboratory from 1937-39. He returned to the United States in 1939, worked in the Harvard University Underwater Sound Laboratory, then transferred to Penn State in 1947. Here he joined the Department of Electrical Engineering and served as head and as the first departmental A. Robert Noll Professor until his retirement in 1971.

In 1949 he founded the Ionosphere Research Laboratory, later to become the

Communications and Space Sciences Laboratory at Penn State, served as its director until his retirement, and continued an active participation until his death. Of particular note was his policy of bringing together a group of outstanding international scientists as resident consultants to the laboratory, a program that proved immensely productive in engaging both staff and students in cooperative research activities in important new fields of study. He was chairman of the U. S. National Committee of URSI in 1954 and was a member of the U. S. National Committee for the IGY, the NSF Advisory Panel of the IQSY, and the National Academy of Sciences Geophysical Research Board Panel on the IQSY. He was a member of the National Academy of Sciences Space Science Board Committee on Atmospheres of the Earth and the Planets and also served as chairman of the NSF Advisory Panel on Atmospheric Sciences. He was a Fellow of the IEEE and a member of the National Academy of Engineering.
