The University of Scranton Virtual HamSCI Workshop The fourth annual HamSCI Workshop 2021 for amateur radio operators and professional scientists will be held in a virtual format on Friday and Saturday, March 19-20. The University of Scranton will serve as host for the Zoom webinar, sponsored by the National Science Foundation (NSF), that will include addresses by guest speakers, poster presentations and demonstrations of relevant instrumentation and software. Participation is free through support from the NSF and the University. The theme of this year’s workshop is midlatitude ionospheric science. The workshop will also serve as a team meeting for the HamSCI Personal Space Weather Station project, which is a NSF funded project awarded to University of Scranton physics and electrical engineering professor Nathaniel Frissell, Ph.D. The project seeks to harness the power of a network of licensed amateur radio operators to better understand and measure the effects of weather in the upper levels of Earth’s atmosphere. The workshop’s keynote address on the “History of Radio” will be given by Elizabeth Bruton, Ph.D., curator of technology and engineering at the Science Museum of London. She will discuss the history, science, technology and licensing of radio amateur communities from the early 1900s through to the present day, exploring how individuals and communities contributed to “citizen science” long before the term entered popular usage in the 1990s. Dr. Bruton has been a non-licensed member of Oxford and District Amateur Radio Society since 2014 and their web manager since 2015. J. Michael Ruohoniemi, Ph.D., professor of electrical and computer engineering at Virginia Tech and principal investigator of the Virginia Tech SuperDARN Initiative, will review the physics of the midlatitude ionosphere and discuss ways in which the amateur radio community can contribute to advancing scientific understanding and technical capabilities. Joe Dzekevich K1YOW, an amateur radio citizen scientist who recently published his work in CQ Magazine, will present “Amateur Radio Observations and The Science of Midlatitude Sporadic E.” The event will also include virtual oral presentations by researchers from NASA Goddard Space Flight Center, MIT Haystack Observatory, the University of Oslo, the University of Bath, Case Western Reserve University, Dartmouth College. the University of Alabama, Clemson University, the New Jersey Institute of Technology and The University of Scranton, among others. University students Veronica Romanek (KD2UHN), Hampton, New Jersey; Cuong Nguyen, Ashley; and M. Shaaf Sarwar (KC3PVF), Lahore, Punjab, are among the iposter presenters.
