Predicted and measured arrival rates of meteors over forward-scatter links.

open access: yes, 1991
Thesis (Ph.D.)-University of Natal, Durban, 1991.Investigations into currently accepted methods of modelling variations in the arrival rate of meteors over forward-scatter meteor links have revealed some shortcomings.

Unsupervised Deep Representation Learning for Infrasound Phase Identification

open access: yesEarth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Infrasound phase identification is challenging because atmospheric variability strongly influences signal propagation on short timescales that are not resolved by standard atmospheric models. While traditional approaches rely on propagation modeling and array‐derived parameters, recent work suggests that waveform structure itself encodes ...

Late Jurassic Carbon Isotope Excursion (Middle Oxfordian Event) Paces With Astronomical Forcing in the Northwestern Tethys

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Marine carbonate carbon isotopes (δ13C), over orbital to multi‐million‐year timescales, provide critical insight into the carbon cycle connecting Earth's atmosphere, lithosphere, hydrosphere and biosphere. However, the influence of astronomical forcing on deep time carbon cycle dynamics remains poorly constrained.

What Observations Would an Energetic Neutral Atom Imager Have Made During the Voyager 2 Flyby of Uranus?

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

Detection of spectral UV from meteors by a nanosatellite

open access: yes, 2014
International audienceHere, we present a cubesat space mission concept devoted to the UV detection of meteors from space. Space observations have the advantages of being able to continuously observe meteors independently of weather conditions on large ...

Impacts of E‐Region Neutral Wind Shear on Equatorial Plasma Bubbles: SAMI3 Simulations Including Metal Ions

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The vertical shear of horizontal neutral winds plays an important role in forming dense metallic layers in the E region. Previous studies suggest that metal ion layers may inhibit equatorial plasma bubble (EPB) development by enhancing E‐region Pedersen conductivity.
