Ionospheric occultation constellation: Global monitoring and simulation

open access: yes地球与行星物理论评, 2022
As we all know, the solar radiation can cause ionospheric disturbances such as ionospheric storms, which have great influence on short wavelength communication and satellite navigation. As a result, the global ionospheric monitoring is very important for

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Ionosphere Monitoring with Remote Sensing

open access: yesRemote Sensing, 2022
Characterising the physical properties of the Earth’s ionosphere is fundamental to shed light on the dynamic processes occurring therein on a wide range of both spatial and temporal scales and to understand several phenomena relevant to Space Weather [...

On the new modes of planetary-scale electromagnetic waves in the ionosphere [PDF]

open access: yesAnnales Geophysicae, 2004
Using an analogy method the frequencies of new modes of the electromagnetic planetary-scale waves (with a wavelength of 103 km or more), having a weather forming nature, are found at different ionospheric altitudes.

ULF Activity in the Earth Environment: Penetration of Electric Field from the Near-Ground Source to the Ionosphere under Different Configurations of the Geomagnetic Field

open access: yesAtmosphere, 2021
The problem with the penetration of electric fields from atmospheric near-Earth electric current sources to the ionosphere is investigated both within the dynamic simulations of the Maxwell equations in the frequency domain and within the simplified ...

IMF dependence of the open-closed field line boundary in Saturn's ionosphere, and its relation to the UV auroral oval observed by the Hubble Space Telescope [PDF]

open access: yes, 2007
We study the dependence of Saturn's magnetospheric magnetic field structure on the interplanetary magnetic field (IMF), together with the corresponding variations of the open-closed field line boundary in the ionosphere.

FEATURES OF IONOSPHERIC EFFECTS FROM THE PARTIAL SOLAR ECLIPSE OVER THE CITY OF KHARKIV ON 10 JUNE 2021 [PDF]

open access: yesRadio Physics and Radio Astronomy, 2021
Purpose: Solar eclipses pertain to high-energy sources of disturbance in the subsystems of the Sun–interplanetary-medium–magnetosphere–ionosphere–atmosphere–Earth and the Earth–atmosphere–ionosphere–magnetosphere systems.

Influence of an Upstream Dynamic Pressure Pulse on Venus–Solar Wind Interaction by Multispecies Magnetohydrodynamic Simulation

open access: yesThe Astrophysical Journal, 2023
As an unmagnetized planet, Venus does not have a global dipole magnetic field like Earth. The solar wind interacts directly with the Venusian ionosphere.

Magnetosphere-Ionosphere Coupling: Implications of Non-Equilibrium Conditions

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The response times of the coupled magnetosphere-ionosphere-thermosphere system are, on average, greater than the autocorrelation timescales of solar wind forcing. This means that the system is rarely, if ever, in equilibrium.
