Large-scale traveling ionospheric disturbances (LSTID) are variations in the ionosphere with wavelengths greater than 1000 kilometers and periodicities between 30 minutes and 3 hours. Ionospheric electron density fluctuations associated with LSTIDs directly affect radio wave propagations passing through the ionosphere and can therefore be detrimental to telecommunications and satellite navigation systems.

Fressel et al. [2022] show how participatory amateur radio observations can be used to study continental-scale ionospheric disturbances in the near-Earth space environment. They found that LSTID signatures in amateur radio data correlate well with observations made by professional scientific instruments, such as high-frequency coherent scatter radars and ground-based GSP receivers. This study demonstrates that citizen science observations are vital for ionospheric research and monitoring.
