Dawn‐Dusk Asymmetries in the Martian Upper Atmosphere
Journal of Geophysical Research: Planets, 2019In this paper, we report the first comprehensive observations of local time asymmetries in densities and scale heights (temperatures) of the Martian upper atmosphere (between 150 and 300 km) measured by the Mars Atmosphere and Volatile Evolution mission ...

Dust injection into the Martian atmosphere
Icarus, 1975The sequence of events culminating in a global Martian dust storm is reviewed in the light of current theories on dust storm generation. Based upon experimental results, a mechanism for the initiation of global dust storms on Mars is proposed. According to this mechanism, the diurnal variation of surface temperature results in desorption of adsorbed ...

A discussion of Martian atmospheric dynamics
Planetary and Space Science, 1967Abstract We have computed radiative relaxation times for temperature perturbations in CO 2 with small admixtures of water vapor under conditions which are similar to those occurring in the martian atmosphere. Certain aspects of the influence of radiative transfer on dynamical phenomena in the martian atmosphere are discussed in terms of these ...

On the abundance of NO2 in the Martian atmosphere
Icarus, 1975Abstract Spectrophotometric scans of Mars and the Moon in the region 4000–5000 A were obtained and ratioed. No evidence of any absorption greater than 3% is visible in the Martian spectrum. Using our own laboratory spectra of NO 2 as well as the published work of Hall and Blacet (1952) we confirm Marshall's (1964) upper limit of 8 μm atmospheres

[1] We present details of an approach to creating a k-distribution radiative transfer model (KDM) for use in the Martian atmosphere. Such models preserve the accuracy of more rigorous line-by-line models, but are orders of magnitude faster, and can be ...

Spacecraft Observations of the Martian Atmosphere
Annual Review of Earth and Planetary Sciences, 2008Recent spacecraft observations of the Martian atmosphere show that the current climate has a distinct and generally repeatable pattern of seasonal and spatial variations. The half of the year that Mars is closest to the Sun is characterized by warm, dusty conditions, whereas the opposite season is relatively cool, free of dust, and dominated by a low ...

A new look to the Martian atmosphere
Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1974Although the Martian atmosphere is at present only about 1% as dense as the Earth’s atmosphere it has been revealed as a dramatically active environment by the observations made during 1971-72 by theMariner9 and SovietMars2 and 3 spacecrafts which arrived at the planet during a major global dust storm. Local dust storms were seen to change in intensity
