A density-temperature description of the outer electron radiation belt during geomagnetic storms [PDF]

, 2009
Bi-Maxwellian fits are made to energetic-electron flux measurements from seven satellites in geosynchronous orbit, yielding a number density (n) and temperature (T) description of the outer electron radiation belt.

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.

Evaluation of E Layer Dominated Ionosphere Events Using COSMIC/FORMOSAT-3 and CHAMP Ionospheric Radio Occultation Data [PDF]

, 2020
At certain geographic locations, especially in the polar regions, the ionization of the ionospheric E layer can dominate over that of the F2 layer. The associated electron density profiles show their ionization maximum at E layer heights between 80 and ...

Research on the effects and related mechanisms of geomagnetic storm on depression

Brain Research Bulletin
Objective: Depression has become disabling disease in the world. Geomagnetic storm is closely related to depression behavior, and melatonin is an important factor in the pathogenesis of depression. This study observed the effects of different intensities

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 ...

Transequatorial magnetic flux loops on the sun: a possible new source of geomagnetic storms

Antarctic Record, 2009
Following the traditional way of expression, geomagnetic storms have been classified into three types; flare-type Sc storms, CH-type Sg storms, and DB-type Sc storms (Sc:sudden commencement;CH:coronal hole;g:gradual;DB:disparition brusque).We have ...

Sporadic Aurora near Geomagnetic Equator: In the Philippines, on 27 October 1856 [PDF]

, 2018
While low latitude auroral displays are normally considered to be a manifestation of magnetic storms of considerable size, Silverman (2003, JGR, 108, A4) reported numerous "sporadic auroras" which appear locally at relatively low magnetic latitudes ...

Study of the Tidal Variations in the Ionosphere and the MLT Region over Mohe and Beijing During Six Intense Geomagnetic Storms from 2016 to 2021

Remote Sensing
Geomagnetic storms can cause large variations in the ionosphere, but their impacts on the mesosphere and lower thermosphere (MLT) are not well understood. Based on the Total Electron Content (TEC) data and the meteor neutral winds data over Mohe (53.5°N,

Relationship between geomagnetic storms and occurrence of ionospheric irregularities in the west sector of Africa during the peak of the 24th solar cycle

Frontiers in Astronomy and Space Sciences, 2022
The study of ionospheric irregularities is important since many technological systems might be influenced by the ionosphere. In this work, we use data from the Global Navigation Satellite Systems (GNSS) receiver installed in Abuja, Nigeria, GPS ...
