High‐Latitude Electrodynamics and Thermospheric Density Variations During the 2024 Gannon Storm

Space Weather, Volume 24, Issue 2, February 2026.
Abstract This study investigates high‐latitude electrodynamics and thermospheric density variations during the 2024 Gannon's storm. First, the auroral precipitation module of Auroral Spectra and High‐Latitude Electric field variabilitY, ASHLEY‐A, is improved to more accurately capture the location of auroral precipitation observed during this ...

Atmospheric Specifications for Infrasound Studies: 1. Operational Analyses

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.
Abstract Operational analysis products issued by weather services are needed for the Comprehensive Nuclear‐Test‐Ban Treaty's (CTBT) infrasound monitoring activities. They provide atmospheric specifications as high as 80 km altitude. They are used to feed propagation simulations designed to characterize sources of interest.

Doppler shift system [PDF]

, 1974
A system is described for measuring velocities of radiating particles based on Doppler shift. Light from the particles is directed through a narrow band optical filter to a Fabry-Perot interferometer initially tuned to a selected center line ...

One-shot x-ray detection based on the instantaneous change in the refractive index of GaAs

AIP Advances, 2020
An interferometric semiconductor x-ray detection system is proposed in this paper. The system is based on the RadOptic effect, and it utilizes Fabry–Perot interferometry to measure radiation-induced changes in the optical refractive index of a ...

Measurement of Optical Response of a Detuned Resonant Sideband Extraction Interferometer

, 2006
We report on the optical response of a suspended-mass detuned resonant sideband extraction (RSE) interferometer with power recycling. The purpose of the detuned RSE configuration is to manipulate and optimize the optical response of the interferometer to

Fabry–Perot interferometer as a solar background noise suppressor: application to daytime lidar

Annals of Geophysics, 2012
Continuous atmospheric probing by a lidar is a requirement for many applications. However, due to high solar background noise during the daytime, lidar operations are mostly restricted to night-time.

Anyons and the quantum Hall effect - a pedagogical review

, 2007
The dichotomy between fermions and bosons is at the root of many physical phenomena, from metallic conduction of electricity to super-fluidity, and from the periodic table to coherent propagation of light.
