Impacts of Cosmic Dust in Planetary Atmospheres
Session ID#: 77563
Session Description:
Recent advances in interplanetary dust measurements and modeling provide much improved estimates of the fluxes and the origin of cosmic dust particles into planetary (and lunar) atmospheres. Dust dynamics models, combined with chemical ablation models that are underpinned by laboratory studies and tested against radar and optical observations, enable the injection rates of chemical compounds (including metals and organics) into a planetâs atmosphere to be predicted as a function of location and time. This information is essential for understanding a variety of atmospheric impacts, including: the formation of metallic layers, meteoric smoke particles and ice cloud nucleation on Earth and Mars; perturbations to atmospheric composition in the giant planets and their satellites; and the supply of biologically important organics, phosphorus and iron to planetary surfaces. Contributions on all aspects of this topic â observations both in interplanetary space and atmospheres, laboratory studies and modeling - are invited.
