Directions of Martian Dust Devils Movement Inferred from Automatic Detection of Their Tracks Using Mathematical Morphology
نویسندگان
چکیده
An automatic method for detecting martian dust devils tracks and inferring their movement directions from digital images is presented. The method is strongly based on Mathematical Morphology theory. The work aims to increase understanding about active aeolian processes on the planet, which may contribute to explain similar processes occurring on Earth. Besides, the results can be used to improve knowledge about risk areas, which is essential to plan manned missions. Two Mars Global Surveyor Mars Orbiter Camera images were used as study areas. For detecting the tracks the next steps were followed: preliminary filtering, enhancing and binarization. For inferring directions morphological granulometric analysis was carried out.

Mars: Dust Devil Tracks in Hellas Basin and Argyre Planitia
Introduction: Dust devils on Mars could be an important mechanism for delivery of dust into the Martian atmosphere. Suspended dust in the Martian atmosphere is observed to be ~1-2μm in diameter [1,2,3] and calculations of fall-out rate [4,5] imply an ongoing supply of this fine dust to the atmosphere. Laboratory wind tunnel experiments [6,7], however, suggest that entrainment of fine dust into ...

Introduction: During the summer of 1976 Viking Lander 1 and 2 touched down at Chryse Planitia and Utopia Planitia, Mars respectively. The primary aim of both Viking Landers was to look for the presence of organic life on the surface of Mars, however each Lander also had a comprehensive meteorological package to monitor the martian atmospheric conditions [1]. The meteorological package consisted...

Dust devils occur in arid climates on the Earth and ubiquitously on Mars, where they likely dominate the supply of atmospheric dust and influence climate. Martian dust devils have been studied with a combination of orbiting and landed spacecraft, while most studies of terrestrial dust devils have involved manned monitoring of field sites, which can be costly both in time and personnel. As an al...

[1] Triboelectric charging of saltating and colliding sand and dust particles produces strong electric fields in terrestrial dust devils and dust storms. Acceleration of the charged particles, as well as microdischarges between them, generates wideband electromagnetic radiation. Similar phenomena are expected to be ubiquitous on Mars, because Martian dust devils and dust storms are larger, stro...
