For over 30 years it has been recognized that atmospheric gravity waves (AGWs) in the 80–
110 km region significantly perturb the basic atmospheric state, perhaps causing instability …

Current perspective and in-situ analyses using data from NASA's twin Solar TErrestrial
RElations Observatory (STEREO) spacecraft have focused studies on ways to provide three …

Ground flashes with positive polarity associated with both sprites and elves excite the Earth's
Schumann resonances to amplitudes several times greater than the background …

This paper presents a summary of 630.0 nm emission observations made by the Cornell All‐
Sky Imager that have revealed an abundance of structure in the midlatitude thermosphère …

We have launched into near-Earth orbit a solar mass-ejection imager (SMEI) that is capable
of measuring sunlight Thomson-scattered from heliospheric electrons from elongations to as …

During the Spread F Experiment campaign, under NASA Living with a Star (LWS) program,
carried out in the South American Magnetic Equator region from 22 September to 8 …

Gravity waves in the mesopause region (80–105 km) may induce perturbations in OH
Meinal Band emissions at∼ 87 km. These perturbations can be observed by ground‐based …

A total of 209 events of quasi-monochromatic atmospheric gravity waves (QMGWs) were
acquired over 5 years of gravity waves (GWs) observation in southern Brazil. The …

The first no‐gap OH airglow all‐sky imager network was established in northern China in
February 2012. The network is composed of six all‐sky airglow imagers that make …

Over the past 60 years, ground-based remote sensing measurements of the Earth's
mesospheric temperature have been performed using the nighttime hydroxyl (OH) emission …
