The Impact of Polar Vortex Strength on the Longitudinal Structure of the Noontime Mid-Latitude Ionosphere and Thermosphere

Remote Sensing
Ground-based ionospheric, CHAMP/STAR, and GOCE satellite neutral density ρ observations under deep solar minimum conditions were used to find whether there is a dependence of longitudinal variations on polar vortex strength. Ionospheric stations at fixed-

Toward Real‐Time Assessment of Infrasound Event Detection Capability Using Deep Learning‐Based Transmission Loss Estimation

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 19, 16 October 2025.
Abstract Accurate modeling of infrasound transmission loss is crucial for assessing the performance of the International Monitoring System, which monitors compliance with the Comprehensive Nuclear‐Test‐Ban Treaty by detecting atmospheric explosions. This modeling supports the design and maintenance of the operating monitoring network.

Heating efficiency in hydrogen-dominated upper atmospheres

, 2014
Context. The heating efficiency is defined as the ratio of the net local gas-heating rate to the rate of stellar radiative energy absorption. It plays an important role in thermal-escape processes from the upper atmospheres of planets that are exposed to

The Performance of DIXSG on Characterizing Global and Regional Ionospheric Disturbances Utilizing Geodetic Receiver Network‐A Case Study

Space Weather, Volume 23, Issue 10, October 2025.
Abstract As the 25th solar cycle enters a highly active phase, the resulting ionospheric irregularities induce disturbances in signals of Global Navigation Satellite System (GNSS), significantly disrupting its global stable positioning, navigation, and timing services.

Towards a global model of the martian atmosphere [PDF]

, 2003
In an effort to continuously improve the capabilities of the Martian atmospheric predictions at LMD, the GCM has been extended into thermospheric heights thus creating the first model to self-consistently couple the lower and upper regions of the ...

Characteristics of Large‐Scale Traveling Ionospheric Disturbances During the 10 May 2024 Geomagnetic Storm

Space Weather, Volume 23, Issue 10, October 2025.
Abstract Based on the total electron content (TEC) observation in the Asian‐Australian and American sectors, this paper investigates the characteristics and hemispheric asymmetry of large‐scale traveling ionospheric disturbances (LSTIDs) during the 10 May 2024 superstorm. We found that the amplitudes and meridional phase velocities of LSTIDs in the two

Artificial Neural Network Model of High‐Latitude Ionospheric Electric Potential: Hemispheric and Equinoctial Asymmetries

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract The high‐latitude ionospheric electric field plays a key role in ionospheric plasma dynamics and energetics. Various ground‐ and satellite‐based observations have been utilized to develop empirical models of the convection electric field. Empirical modeling typically relies on statistical regression techniques, where predefined functions are ...
