The global O2 airglow field as seen by the MATS satellite: strong equatorial maximum and planetary wave influence [PDF]

open access: yesAtmospheric Chemistry and Physics
The Mesospheric Airglow/Aerosol Tomography and Spectroscopy (MATS) satellite was launched in November 2022, carrying as its main instrument a limb-viewing telescope with six spectral channels designed to image atmospheric O2 airglow and noctilucent ...

Analysis of 2D airglow imager data with respect to dynamics using machine learning [PDF]

open access: yesAtmospheric Measurement Techniques, 2023
We demonstrate how machine learning can be easily applied to support the analysis of large quantities of excited hydroxyl (OH*) airglow imager data. We use a TCN (temporal convolutional network) classification algorithm to automatically pre-sort images ...

Studying a Long-Lasting Meteor Trail from Stereo Images and Radar Data

open access: yesAtmosphere, 2021
Unique observation of a long-lasting meteor trail of about half an hour duration is described. The trail resulted from a burning meteor from the Leonid storm flux in the middle latitudes over eastern Siberia.

Space-Based Limb-Imaging Spectrometer for Atmospheric O2 Airglow Detection

open access: yesAtmosphere
This paper presents a space-based limb-imaging spectrometer (LIS) for detecting atmospheric O2 airglow; it scans the atmosphere with a vertical range of 10–100 km and has a vertical resolution of 2 km. The LIS’s detection performance needs to be examined

Automated Detection and Tracking of Equatorial Plasma Bubbles Utilizing Global‐Scale Observations of the Limb and Disk (GOLD) 135.6 nm Data

open access: yesEarth and Space Science, 2023
Equatorial plasma bubbles (EPBs) are regions of depleted plasma within the ionosphere that form during post‐sunset hours near the magnetic equator. EPBs tend to align with local geomagnetic field lines, extend hundreds of kilometers along geomagnetic ...

Variability of the Brunt–Väisälä frequency at the OH-airglow layer height at low and midlatitudes [PDF]

open access: yesAtmospheric Measurement Techniques, 2020
Airglow spectrometers, as they are operated within the Network for the Detection of Mesospheric Change (NDMC; https://ndmc.dlr.de, last access: 1 November 2020), for example, allow the derivation of rotational temperatures which are equivalent to the ...

Inversion of Wind and Temperature from Low SNR FPI Interferograms

open access: yesRemote Sensing, 2023
The temperature and wind in the middle and upper atmosphere can be obtained by recording the Doppler shift and broadening of the airglow emission, which is reflected by the interference ring from a ground-based Fabry–Perot interferometer (FPI) system ...

Airglow

open access: yesEos, Transactions American Geophysical Union, 1971
The past 4 years have seen the continuation of considerable activity in airglow research. Patterns of changing emphasis are becoming clear, observations are tending to become more selective, and changes in technique have led to regular observations of dayglow, line widths in the nightglow, and observations in the middle and far ultraviolet, detection ...

Jovian Auroral Proton Precipitation

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The total power of the Jovian aurora is about 1013–1014 W with ultraviolet emission observed in the Lyman and Werner bands of molecular hydrogen. X‐ray, radio, and infrared emissions have also been observed. The Jovian Auroral Distributions Experiment and the Jovian Energetic Particle Detector Instrument onboard the Juno spacecraft, orbiting ...
