Meteors and Dusty Plasma Phenomena in Planetary Atmospheres

Meteor observations reveal the orbits and properties of small solar system objects and provide unique opportunities to study physical phenomena in the Earth's atmosphere. The amount of cosmic dust that enters the Earth's atmosphere is uncertain and estimates differ by almost two orders of magnitude. A large fraction of the meteoric material remains in the atmosphere for long time, forms new nm-sized particles, contributes to formation of ice particles, dusty plasma, and atmospheric layers. Observations are made with lidar, radar, other optical instruments, and also with rockets or using satellites. Meteors may also occur on other solar system objects and space probes observe the influence of charged nanodust in ionospheric measurements. This session addresses the theoretical, observational, and experimental studies of meteors and phenomena of meteoric dust and nanodust in ionospheres.
