Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.Abstract This study demonstrates the influence of electromagnetic ion cyclotron (EMIC) rising‐tone emissions on relativistic electrons in the inner magnetosphere using data obtained from the Van Allen Probes and Arase satellites. We find that the intense EMIC rising‐tone emissions occur during the increase in the solar wind pressures, creating ...

Modeling the Ionosphere with GPS and Rotation Measure Observations [PDF]
, 2018 The ionosphere contributes time-varying Faraday Rotation (FR) to radio signals passing through it. Correction for the effect of the ionosphere is important for deriving magnetic field information from FR observations of polarized cosmic radio sources, as well as providing valuable diagnostics of the structure of the ionosphere.

Conductance Model for Extreme Events : Impact of Auroral Conductance on Space Weather Forecasts [PDF]
, 2020 Ionospheric conductance is a crucial factor in regulating the closure of magnetospheric field-aligned currents through the ionosphere as Hall and Pedersen currents. Despite its importance in predictive investigations of the magnetosphere - ionosphere coupling, the estimation of ionospheric conductance in the auroral region is precarious in most global ...

The Effect of Water Vapor and Solar Zenith Angle on Oceanic Diurnal Warming
Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.Abstract Oceanic diurnal warm layers have been extensively studied over the years due to their important role in a variety of geophysical disciplines. Much of this research has been dedicated to the development of predictive models of varying complexity to calculate the spatiotemporal magnitude of the effect. This manuscript presents results which show

Diagnostics of plasma in the ionospheric D-region: detection and study of different ionospheric disturbance types [PDF]
, 2017 Here we discuss our recent investigations of the ionospheric plasma by using very low and low frequency (VLF/LF) radio waves. We give a review of how to detect different low ionospheric reactions (sudden ionospheric disturbances) to various terrestrial and extra-terrestrial events, show their classification according to intensity and time duration, and

The effects of crustal magnetic fields and solar EUV flux on ionopause formation at Mars
, 2019 We study the ionopause of Mars using a database of 6,893 ionopause detections obtained over 11 years by the MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) experiment.

Predictions of Auroral Electron Precipitation and Joule Heating at Uranus
Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.Abstract The precipitation of electrons and Joule heating are key processes through which energy is transferred from Uranus' magnetosphere to its upper atmosphere. These processes drive atmospheric ionization, thermospheric heating, and auroral emission at Uranus.
