Buildup with Bremsstrahlung in the Martian Atmosphere
Nuclear Science and Engineering, 2020Photon buildup is a function of energy, medium, and geometry and therefore must be specifically calculated for the case of interest.

Low palaeopressure of the martian atmosphere estimated from the size distribution of ancient craters
, 2013The decay of the martian atmosphere—which is dominated by carbon dioxide—is a component of the long-term environmental change on Mars from a climate that once allowed rivers to flow to the cold and dry conditions of today.

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 ...

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

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 ...

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 ...
