Six medium-scale gravity waves (GWs) with horizontal wavelengths of λ H= 60–160 km were
detected on four nights by Taylor et al.(2009) in the OH airglow layer near Brasilia, at 15° S …

A new study of gravity waves produced by thunderstorms was performed using continuous
recordings at the IS17 (Ivory Coast) infrasound station of the International Monitoring System …

As part of the SpreadFEx campaign, coordinated optical and radio measurements were
made from Brazil to investigate the occurrence and properties of equatorial Spread F, and to …

We present the first coordinated study using two lidars at two separate locations to
characterize a 1 h mesoscale gravity wave event in the mesopause region. The …

The gravity wave (GW) characteristics over Maui from 2002 to 2007 are deduced from OH
airglow imager. The dominant horizontal wavelength falls between 15 and 30 km. Intrinsic …

We present a first detailed climatological study of individual quasi-monochromatic
mesospheric, short-period gravity-wave events observed over Antarctica. The …

The noctilucent clouds (NLC) are high-altitude bright cloud formations visible under certain
conditions from high-latitude places during the summer months. Even if the exact nature of …

All‐sky CCD observations of short‐period mesospheric gravity waves have been made from
Halley Station, Antarctica (76° S, 27° W). On 27 May, 2001, an unusual wave event …

Measurements from the High Resolution Dynamics Limb Sounder (HIRDLS) on NASA's
Aura satellite are used to quantify gravity wave momentum fluxes generated from monsoon …

Terrestrial ecliptic dayside observations of the exospheric Lyman-α column intensity
between 3–15 Earth radii (R e) by UVIS/HDAC at CASSINI have been analysed to derive the …
