Sentences with phrase «of airglows»

Fundamental experimental data were derived from the observations of airglows by the Spectroscopy for Investigation of Characteristics of the Atmosphere of Mars (SPICAM) instrument on - board Mars Express: while NO is useful to constrain dynamics around the 100 km level (Gagné et al. 2013), CO and CO2 + UV emissions allow the direct monitoring of the efficiency of ionization processes (Stiepen et al. 2015).

Based on the team's analyses, they estimate that the 10 - fold - or - more magnification of airglow occurs somewhere on Earth on 7 % of nights, with observers at any one spot able to see a bright night only once per year — and only then if conditions are just right.

There's still some debate though as to whether Steve is a true aurora, or perhaps a form of airglow, which results from the upper atmosphere releasing a tiny amount of light as it is warmed by the sun and the Earth's surface.

Not exact matches

Trapped beneath Earth's ocean of air, ground - based observatories will be stymied by starlight - warping turbulence, and by airglow — faint light emitted by atmospheric chemical reactions that can corrupt delicate observations.

Trapped below Earth's ocean of air, even the largest ground - based observatories will be stymied by starlight - warping turbulence and by airglow, faint light emitted by atmospheric chemical reactions that can corrupt delicate observations.

Processes in the ionosphere also create bright swaths of color in the sky, known as airglow.

Still, at altitudes above roughly 80 kilometers (50 miles) lunar tides have been detected in winds, temperature, airglow emissions and a number of ionospheric parameters.

Two upcoming NASA missions will study airglow and other properties of the ionosphere.

Analyzing measurements of high - altitude airglow gathered by a satellite in 1992 and 1996 (years of maximum and minimum solar flare activity, respectively), the scientists found 11 cases where airglow, in theory, brightened enough to be seen by observers on the ground, they report in Geophysical Research Letters.

From 240 miles above Earth's surface, lightning is visible as bright blotches, and city lights appear as yellow streaks; the atmosphere glows in bands of yellow, green, and red as energetic air molecules interact and emit light, a process (called airglow) that is difficult to see from the ground.

This enormous reservoir of charged particles plays a still - unexplained role as middleman in the interaction of Earth and sun which is reflected in magnetic storms, in the airglow and in the beautiful displays of the aurora.

As evidenced in previous sections, airglow is a manifestation of planetary space weather.

A similar scheme applies to the NO airglow UV emission, ultimately generated after the UV dissociation of CO2 and N2 at the dayside (Stiepen et al. 2013).

In his early stage of research, he was involved in the field of the earth's upper atmosphere like observations of terrestrial airglow and aurora, as well as the ozone layer.

I'm open for new ideas and do not write off the idea of electrical phenomena playing a role in climate — hence a discussion on the subject together with various curiosities such as Aurora, Elves, airglow, Sprites, the Van Allen belts, and Lightening in my book «Solar Activity and Earth's Climate» (2002; Praxis / Springer).
