Tidally Driven Wavenumber‐3 and ‐4 Structures in the Ionosphere‐Thermosphere Observed by ICON and Comparison of Their Coupling Mechanisms

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract We analyze fixed local time, longitudinal wavenumber‐3 (WN3) and wavenumber‐4 (WN4) structures in the low‐latitude F‐region ionosphere using ICON‐IVM observations of ion drifts, temperatures, and densities from Jan 2020 to Jun 2022. These ionospheric wave patterns are compared to non‐migrating tides and stationary planetary waves in the ...

Morphology of the Excited Hydroxyl in the Martian Atmosphere: A Model Study—Where to Search for Airglow on Mars?

open access: yesRemote Sensing
Monitoring excited hydroxyl (OH*) airglow is broadly used for characterizing the state and dynamics of the terrestrial atmosphere. Recently, the existence of excited hydroxyl was confirmed using satellite observations in the Martian atmosphere.

A rocket-borne airglow photometer [PDF]

open access: yes
The design of a rocket-borne photometer to measure the airglow emission of ionized molecular nitrogen in the 391.4 nm band is presented. This airglow is a well known and often observed phenomenon of auroras, where the principal source of ionization is ...

FUSE Observations of the Dwarf Nova SW UMa During Quiescence [PDF]

open access: yes, 2004
We present spectroscopic observations of the short-period cataclysmic variable SW Ursa Majoris, obtained by the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite while the system was in quiescence.

Low latitude airglow

open access: yesJournal of Earth System Science, 1983
Tropical airglow work during the last few years is reviewed. Airglow instrumentation is becoming more complex. Some of these sophisticated airglow experiments giving important information about the upper atmosphere such as ionospheric F region electron density, height of maximum electron density, dynamics of and irregularities in the F region ...

Impact of lower atmospheric scattering on ground-based optical thermospheric wind observations with spatially uneven airglow [PDF]

open access: yesAtmospheric Measurement Techniques
Scattered airglow emissions in the lower atmosphere can bias ground-based interferometer observations of thermospheric winds, particularly when airglow brightness becomes spatially uneven due to auroras. During two geomagnetic storms with visible auroras

Study on the Imaging Interference of a Vortex-Light-Modulated Gaussian Beam

open access: yesPhotonics
Combined with vortex light and airglow, some different physical phenomena are presented in this paper. Based on the ground-based airglow imaging interferometer (GBAII) made by our group, a liquid crystal on silicon (LCoS) device on one arm of a wide ...

Nightside Detection of a Large‐Scale Thermospheric Wave Generated by a Solar Eclipse

open access: yesGeophysical Research Letters, 2018
The generation of a large‐scale wave in the upper atmosphere caused by a solar eclipse was first predicted in the 1970s, but the experimental evidence remains sparse and comprises mostly indirect observations. This study presents observations of the wind
