Development of ground-based search -coil magnetometer systems in the polar regions and studies of ULF Pc 1--2 wave propagation in the ionospheric waveguide
… have been developed for the observations of geomagnetic pulsations in the ultra low frequency (ULF) range (a few mHz to a few Hz). The design, fabrication, and test/calibration have been performed to detect very weak geomagnetic pulsations with approximately a few pT resolution over the …

Energy deposition in the lower auroral ionosphere through energetic particle precipitation
… measurements and ground-based observations of geomagnetic pulsations. The riometer showed varying movements of the absorption patches through the case study and a determination of different dominating particle drift regimes was possible through comparison with coherent HF radar. A statistical …

Occurrence Statistics and Driving Mechanisms of Ionospheric Ultra-Low Frequency Waves Observed by SuperDARN Radars
… We begin in Chapter 2 with a case study of Pi2 pulsations which are short-duration (5-15 min) damped geomagnetic field oscillations with periods of 40-150 s. Simultaneous observations of Pi2 pulsations from THEMIS spacecraft, midlatitude SuperDARN radars, and ground magnetometers, together with …
