Productino of KSR-III Airglow Photometers to Measure MUV Airglows of the Upper Atmosphere Above the Korean Peninsular

Journal of Astronomy and Space Sciences, 2002
We have constructed two flight models of airglow photometer system (AGP) to be onboard Korea Sounding Rocket-III (KSR-III) for detection of MUV dayglow above the Korean peninsular.

Baseline Climatology of Gravity Waves From ∼30 to ∼70 km Established With Lidar Observations Over a Decade at McMurdo (77.84°S, 166.67°E), Antarctica: Implications for Vertical Wave Evolution

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Lidar observations of atmospheric gravity waves (GWs) have been made spanning 14 years above McMurdo Station, Antarctica. Using these extensive observations and interleaved data processing techniques which enable bias‐free/noise‐floor‐free estimation of GW parameters, this study forms seasonal baselines for GW potential energy densities (Epm ...

Gravity waves in the middle atmosphere: Recent progress and needed studies [PDF]

, 1986
The recent recognition of the important role played by gravity waves in the large-scale circulation and thermal structure of the mesosphere and lower thermosphere has stimulated considerable research on their properties and their middle atmosphere ...

A Survey of Atmospheric Gravity Waves Observed by GOLD During Quiet to Moderate Solar and Geomagnetic Activity

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Atmospheric gravity waves (GWs) are believed to transport energy and momentum between different regions of the atmosphere. Historically, observations of these waves from both ground and space have been relatively abundant at altitudes up to the lower thermosphere, and somewhat less abundant in the upper thermosphere and F‐region ionosphere ...

Detection of wave activity in measurements of thermospheric vertical winds and temperatures at subauroral latitudes

Frontiers in Astronomy and Space Sciences
The need for high precision measurements of vertical winds with uncertainties on the scale of 3–5 m s−1 and a temporal cadence of 1–2 min to achieve detection of gravity wave (GW) structure has made it exceedingly difficult to study the response of the ...

Daily Variability in the Terrestrial UV Airglow

Atmosphere, 2020
New capability for observing conditions in the upper atmosphere comes with the implementation of global ultraviolet (UV) imaging from geosynchronous orbit. Observed by the NASA GOLD mission, the emissions of atomic oxygen (OI) and molecular nitrogen (N2)

Basic Features of Global Circulation in the Mesopause Lower Thermosphere Region [PDF]

, 1984
D1 and D2 techniques have been used and are being used for observations at stations located in the high, middle, and low latitudes of both hemispheres. The systematical and wind velocity measurements with these techniques make it possible to specify and ...

Evolution of Ionospheric Ion Upflow Flux During the April 2023 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract We study the impact of the evolving magnetosphere‐ionosphere‐thermosphere system on upward ion fluxes during the 23–24 April 2023 geomagnetic storm. This storm has a “double‐dip” structure where two southward IMF Bz ${\mathrm{B}}_{z}$ periods cause two dips in the SYM‐H index.
