Connecting Amateur Radio and Atmospheric Science: The CEDAR Madrigal Database

The CEDAR Madrigal database is a cornerstone repository for upper atmospheric research, providing open, standardized access to a vast archive of geospace observations. Catering specifically to the Coupling, Energetics, and Dynamics of Atmospheric Regions (CEDAR) research community, Madrigal integrates data from a global network of instruments—including incoherent scatter radars, ionosondes, Fabry–Perot interferometers, GNSS receivers, magnetometers, and recently, aggregated PSKReporter, WSPRNet, and RBN data collected and provided by members of the amateur radio community.
