Mars possesses dynamical features called polar vortices: regions of cold, isolated air over the poles circumscribed by powerful westerly jets which can act as barriers to transport dust, water, and chemical species. The 2018 Global Dust Storm was observed multiple orbiters offered a valuable opportunity study effects such storm on dynamics. To this end, we assimilate data from Climate Sounder A...

[1] Dust radiative effects and atmospheric heating rates are investigated for a Saharan dust storm on 21 June 2007 using a combination of multiple satellite data sets and ground and aircraft observations as input into a delta-four stream radiative transfer model (RTM). This combines the strengths of the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations and CloudSat satellites a...

Viking landers 1 and 2 measured the surface pressure on Mars for multiple annual cycles and found that Mars’ CO2 cycle is highly repeatable [1]. The dust cycle can affect the CO2 cycle by altering the heat balance of the atmosphere and by modifying the emissivity and albedo of the polar caps [2, 3]. One would therefore expect that the highly variable nature of the dust cycle would lead to year-...

Dust storm is one of the criteria for air pollution, and pollution by Heavy Metal(HM) is one of the major environmental problems in the world. The objective of the present study was to assess some of HMs concentrations in the leaves and bark of cypress and atmospheric falling dust along the Yazd highway, Yazd Province, Iran. The total concentrations of cadmium (Cd), cobalt (Co), copper (Cu), ni...

In 1929 Storm Van Leuven published his results on treatment of asthma using a “climate chamber.” His design of a room included maintaining low dust levels and a supply of clean air. This experiment was based on the observation that many asthmatics improved when they spent time in the high altitude clinics in Switzerland (1). It was also well known .50 years ago that patients with asthma improve...

This paper address the detection of dust storms based on a probabilistic analysis of multispectral images. We develop a feature set based on the analysis of spectral bands reported in the literature. These studies have focused on the visual identification of the image channels that reflect the presence of dust storms through correlation with meteorological reports. Using this feature set we dev...

[1] Dust devils are significant meteorological phenomena on Mars: They are ubiquitous, continually gardening the Martian surface, and may be the primary atmospheric dustloading mechanism in nonstorm seasons. Further, dust grains in the swirling dust devils may become electrically charged via triboelectric effects. Electrical effects associated with terrestrial dust devils have been reported pre...

A farmer and his two sons during a dust storm in Cimarron County, Oklahoma, 1936, Photo: Arthur Rothstein The Dust Bowl, or the Dirty Thirties, was a period of severe dust storms causing major ecological and agricultural damage to American and Canadian prairie lands in the 1930s, particularly in 1934 and 1936. The phenomenon was caused by severe drought coupled with decades of extensive farming...
