OH airglow imaging observations of a mesoscale gravity wave generated by jet streams near the Tibetan Plateau region

Earth and Planetary Physics
In this study, we investigate the source and dynamics of a mesoscale gravity wave (MGW) observed over northern China. On January 12, 2010, an OH airglow imager at the Xinglong station (40.2°N, 117.4°E) detected an MGW propagating from southwest to ...

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

Atmospheric 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

OMTI Airglow Temperature Photometer (ATP) at Rikubetsu, Japan

, 2014
Optical Mesosphere Thermosphere Imagers (OMTIs) Airglow Temperature Photometer (ATP) Data. The ATP measures airglow rotational temperature and airglow intensity in the mesopause region at 80-100km altitudes through the OH and O2 airglow emission lines.

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 ...

Heater‐induced ionization inferred from spectrometric airglow measurements

, 2014
Spectrographic airglow measurements were made during an ionospheric modification experiment at High Frequency Active Auroral Research Program on 12 March 2013. Artificial airglow enhancements at 427.8, 557.7, 630.0, 777.4, and 844.6 nm were observed.

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

Remote 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.
