Equatorial Ionospheric VTEC Perturbations During the 21 June 2020 Solar Eclipse

open access: yesEarth and Space Science, Volume 12, Issue 12, December 2025.
Abstract The annular solar eclipse of 21 June 2020, provided a valuable opportunity to examine the ionospheric response to celestial events. This study analyzes variations in Vertical Total electron content (VTEC) over the equatorial region using data from the UQRG Global Ionospheric Map (GIM), ground‐based GPS‐TEC measurements, and equatorial ...

VLF Remote Sensing Across and Along the Totality Path During the 8 April 2024 Total Solar Eclipse Using a VLF Receiver Network

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract During the total solar eclipse in the United States on 8 April 2024, we observed the amplitude and phase of Very Low Frequency (VLF) signals from five U.S. Navy VLF transmitters using a novel geometry of VLF receivers deployed along and across the totality path.

Thermospheric Nitric Oxide Density From SABER: Local Time Dependence and Validation Against Independent Observations

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract The Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) nitric oxide (NO) concentration is a newly derived data set from SABER NO emission rate measurements, covering altitudes from 120 to ∼250 km with full local time coverage.
