Making Amateur Radio Data for Space Weather Research Available in the CEDAR Madrigal Database

Recent work has shown that data collected from amateur radio monitoring reports is useful for ionospheric research and studying the effects of terrestrial and extra-terrestrial events on radio propagation. In ongoing NASA and NSF-sponsored projects, we collect data (from 2016 to present) from the three major amateur radio databases: the Reverse Beacon Network, the Weak Signal Propagation Reporting Network, and PSK Reporter, receiving over 150 million data points per day. We convert the various signal report formats into a single standard layout and now have a system running which produces output files for importing into the MIT Haystack CEDAR Madrigal Geospace Database thus making the data freely available to researchers everywhere. So, far, we have used this data collection (now approaching 10 terabytes) to observe and analyze Large Scale Traveling Ionospheric Disturbances and their related climatology, as well as study the effects of phenomena such as the Tonga eruption on the ionosphere and the Oct. 9, 2022 gamma ray burst.
