About the Group

The Perry Group explores the Magnetosphere-Ionosphere-Thermosphere (MIT) system, investigating the plasma dynamics and "space weather" effects that impact critical communications and sensing infrastructure. Supported by the National Aeronautics and Space Administration (NASA), the Office of Naval Research (ONR), the National Science Foundation (NSF), and the Amateur Radio Digital Communications (ARDC), our team utilizes both remote sensing and in situ techniques to diagnose geospace environments. We are also committed to interdisciplinary research and citizen science, leading international initiatives like the STEVE Community Workshop and collaborating with Ham Radio Science Citizen Investigation (HamSCI) to advance our understanding of atmospheric phenomena through community-driven observations.

June tends to be the busiest meeting month

Members of the Perry group were spread out across North America for most of June, attending scientific meetings in Virginia, Iowa, and Saskatchewan (Canada). Drs. Perry and Beser attended the SuperDARN Workshop in Roanoke, Virginia. The very next week Dr. Perry attending the Canadian CAP Congress in Saskatoon, Saskatchewan. And finally, last week Drs. Perry and Pandey participated in the joint CEDAR-GEM Workshop in Des Moines, Iowa. Perry, Pandey, and Beser several papers highlighting exciting results from the multitude of research activities underway in the group.

NJIT hosts a cutting-edge citizen science research conference

NJIT welcomed over 100 in-person and 75 virtual attendees at the 2025 HamSCI Workshop, March 14 - 15, 2025. The two-day event featured over 50 talks, poster presentations, and tech demonstrations, as well as countless hours of stimulating discussions on HamSCI research. The meeting was kicked off by NJIT President, Dr. Teik Lim, who gave a rousing speech which set the tone for the remainder of the meeting. HamSCI is a collective of traditional and citizen scientists who use ham radio to study the natural geospace environment. Members of the Perry Group, including Drs. Perry and Pandey, are part of the HamSCI local organizing committee.

Members of the Perry group will use citizen science data to study eclipse effects

Prof. Perry has been awarded a NASA grant (80NSSC25K7026) to study the effects of the October 2023 and April 2024 solar eclipses and their effects on the terrestrial ionosphere-thermosphere system. The project titled "A HamSCI investigation of the bottomside ionosphere during the 2023 annular and 2024 total solar eclipses" will analyze data collected by HamSCI participants and develop HamSCI's ability to investigate transient heliophysical and geophysical events, such as coronal mass ejections and geomagnetic storms.
