Atmospheric Ionization Caused by EMIC‐Wave Driven Energetic Electron Precipitation at Auroral Latitude

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Electromagnetic ion cyclotron (EMIC) waves are recognized as one of the primary drivers of energetic electron precipitation (EEP) into the Earth's atmosphere. A problematic discrepancy has remained between the occurrence frequency of waves in magnetic local time (MLT) and the resultant precipitation observed by satellites.

Barometric effect of neutron component of cosmic rays at Antarctic station «Mirny»

Solar-Terrestrial Physics, 2016
The barometric effect of cosmic ray neutron component was estimated on the example of the Antarctic station Mirny. We used hourly data from continuous monitoring of neutron component and data from a local weather station for 2007–2014.

LONG-TERM TREND OF THE IONOSPHERIC E-LAYER RESPONSE TO SOLAR FLARES

Solar-Terrestrial Physics, 2022
Using data from ground-based vertical sounding of the ionosphere (VS) at the station Moscow and five Japanese stations for the period from 1969 to 2015, we have examined the long-term response of the E layer to solar X-ray flares.

The Effects of Solar Wind Dynamic Pressure on the Structure of the Topside Ionosphere of Mars

, 2019
We use Mars Atmosphere and Volatile EvolutioN observations of the upstream solar wind, and Mars Express observations of ionospheric electron densities and magnetic fields, to study how the topside ionosphere ($>$ 320 km) of Mars is affected by variations

Super‐Resolution Reconstruction of Near‐Space Global‐Scale Temperature Fields (50–80 km) Utilizing an Extendable Multi‐Input Operator Neural Network Based on Reanalysis Data and Satellite Observations

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract The reanalysis data set between 50 and 80 km altitude suffers from its low vertical resolution and high uncertainty errors. This paper introduces an extendable multi‐input operator neural network, designed to explore global‐scale temperature field to achieve super‐resolution reconstruction in this region.

Magnetospheric convection from Cluster EDI measurements compared with the ground-based ionospheric convection model IZMEM [PDF]

Annales Geophysicae, 2009
Cluster/EDI electron drift observations above the Northern and Southern polar cap areas for more than seven and a half years (2001–2008) have been used to derive a statistical model of the high-latitude electric potential distribution for summer ...

Ionospheric Power-Spectrum Tomography in Radio Interferometry

, 2010
A tomographic method is described to quantify the three-dimensional power-spectrum of the ionospheric electron-density fluctuations based on radio-interferometric observations by a two-dimensional planar array.

Limb sounders tracking topographic gravity wave activity from the stratosphere to the ionosphere around midlatitude Andes [PDF]

, 2015
Several studies have shown that the surroundings of the highest Andes mountains at midlatitudes in the Southern Hemisphere exhibit gravity waves (GWs) generated by diverse sources which may traverse the troposphere and then penetrate the upper layers if ...

A Superposed Epoch Analysis of Two Stage Refilling in the Plasmasphere

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract The cold, dense plasma of the plasmasphere is sourced by outflows from the ionosphere, but the refilling process is still poorly understood. Refilling may occur in stages, and studying this process is important to understanding how the ionosphere couples to the magnetosphere.
