Comparison between indices during geomagnetic disturbances [PDF]
Geofísica Internacional, 2004 Auroral indices AE, AU, AL, and Troshichev index from Thule, PC (Polar Cap) are compared for geomagnetic disturbances of different intensities. To identify perturbations, the indices Dst and AE have been used. Fourteen storms have been analyzed, with Dst

Deep Neural Networks With Convolutional and LSTM Layers for SYM‐H and ASY‐H Forecasting
Space Weather, 2021 Geomagnetic indices quantify the disturbance caused by the solar activity on a planetary scale or in particular regions of the Earth. Among them, the SYM‐H and ASY‐H indices represent the (longitudinally) symmetric and asymmetric geomagnetic disturbance ...

Geomagnetic disturbances analysis using discrete wavelets [PDF]
Geofísica Internacional, 2008 To assess long-term trends and periodicities in geomagnetic storms, the discrete wavelet transform, using the Daubechies function, was applied. Among a variety of techniques, which are available for analyzing variability, wavelet analysis has emerged in ...

Wavelet analysis of geomagnetic jerks [PDF]
, 2013 Geomagnetic jerks, or secular variation impulses, are abrupt changes in the slope of the first time derivative of the Earth's magnetic field. These changes occur on time scales of the order of a year. It has been demonstrated that the jerks might be more

Variation of Total Electron Content over Nepal during Geomagnetic Storms: GPS Observations
Russian Journal of Earth Sciences, 2023 Geomagnetic storms have very profound effects on the Total Electron Content (TEC) of the ionosphere. In order to investigate the equatorial and low-latitude ionospheric response to the geomagnetic storms of varying intensities, a detailed study of ...
