Martian Dust Belts: Waiting for Discovery
Mukai (1992), Krymskii et al. (1992), Tátrallyay et al. (1992), Juhász et al. (1993), Kholshevnikov et al. (1993), In this paper, we present modeling results of the presumed dust belts of Mars. We combine recently obtained theoretical Ishimoto and Mukai (1994), Krivov (1994), Krivov and results in dynamics of circumplanetary dust grains with up-toTitov (1994), Sasaki (1994), Juhász and Horányi ...
متن کاملMass of Dust in the Martian Atmosphere
1 Estimates of the mass of dust suspended in the Martian atmosphere are derived from global and regional 9 pm opacity maps produced from Viking Infrared Thermal Mapper data. During the peak of the 1977b storm, a total dust mass of approximately 101 S gm was suspended, equivalent to 10-3 gm/cm2, or a layer 4 Lm thick. During a local dust storm near Solis Planum at Ls 227°, approximately 3.56 x 1...
متن کاملDetecting electrical activity from Martian dust storms
We present a model addressing the possible electrification of Martian dust storms based on the effective electrical charging of an individual dust grain. An upper charge bound on a grain can be determined based on the grain capacitance in the lowpressure Martian atmosphere. It is assumed that treiboelectric and inductive processes, like that presumed operating in terrestrial dust storms, can el...
متن کاملGravitomagnetic Separation of Bipolar Charged Martian Dust
The possible role of magnetic anomalies on Mars in gravitational enhancement of separation of charged dust is considered. It is known that charges become spatially separated by differential transport and gravitational sedimentation because the charge polarity of particles of dust depends on the particle size—where smaller particles are negatively charged and larger particles are positively char...
متن کاملAssimilating and Modeling Dust Transport in the Martian Climate System
A meteorological data assimilation system has been developed recently for analyzing measurements of temperature and dust opacity on Mars and has been successfully applied in several studies (e.g. Montabone et al. 2005, Lewis et al. 2007) to study various atmospheric phenomena. A more sophisticated data assimilation system, now with full dust transport incorporated, is becoming available to repr...
