Quantifying extreme behaviour in geomagnetic activity [PDF]

, 2011
Understanding the extremes in geomagnetic activity is an important component in understanding just how severe conditions can become in the terrestrial space environment. Extreme activity also has consequences for technological systems.

Continuous underground observation of the geomagnetic field in Xuzhou City, North China, and its time-varying characteristics

Frontiers in Earth Science
Underground space in Xuzhou City, North China, has become a favorable site for continuous geomagnetic observation to reveal geomagnetic-field variations and to monitor seismic activity due to its distinct advantage of an “ultra-quiet” and “ultra-clean ...

Multiscale variation model and activity level estimation algorithm of the Earth's magnetic field based on wavelet packets [PDF]

Annales Geophysicae, 2018
We suggest a wavelet-based multiscale mathematical model of geomagnetic field variations. The model is particularly capable of reflecting the characteristic variation and local perturbations in the geomagnetic field during the periods of increased ...

What happens when the geomagnetic field reverses?

, 2012
During geomagnetic field reversals the radiation belt high-energy proton populations become depleted. Their energy spectra become softer, with the trapped particles of highest energies being lost first, and eventually recovering after a field reversal ...
