Can core-surface flow models be used to improve the forecast of the Earth's main magnetic field? [PDF]
, 2008 [1] Geomagnetic main field models used for navigation are updated every 5 years and contain a forecast of the geomagnetic secular variation for the upcoming epoch. Forecasting secular variation is a difficult task.

Observation of the east-west anisotropy of the atmospheric neutrino flux [PDF]
, 1999 The east-west anisotropy, caused by the deflection of primary cosmic rays in the Earth's magnetic field, is observed for the first time in the flux of atmospheric neutrinos.

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 ...

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.

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 ...

Using neural networks to study the geomagnetic field evolution
Annals of Geophysics, 2008 study their time evolution in years. In order to find the best NN for the time predictions, we tested many different kinds of NN and different ways of their training, when the inputs and targets are long annual time series of synthetic ...
