Journal ArticleDOI
Modeling phase functions for dustlike tropospheric aerosols using a shape mixture of randomly oriented polydisperse spheroids
TL;DR: In this article, the authors used the rigorous T-matrix method to extensively compute light scattering by shape distributions of polydisperse, randomly oriented spheroids with refractive indices and size distributions representative of naturally occurring dust aerosols.
Journal ArticleDOI
Enceladus' Water Vapor Plume
Candice Hansen,Larry W. Esposito,A. I. F. Stewart,Joshua Colwell,Amanda R. Hendrix,Wayne Pryor,Donald E. Shemansky,Robert A. West +7 more
TL;DR: The Cassini spacecraft flew close to Saturn's small moon Enceladus three times in 2005 and observed stellar occultations on two flybys and confirmed the existence, composition, and regionally confined nature of a water vapor plume in the south polar region of Ence Gladus.
Journal ArticleDOI
Cassini imaging of Jupiter's atmosphere, satellites, and rings.
Carolyn Porco,Robert A. West,Alfred S. McEwen,Anthony D. Del Genio,Andrew P. Ingersoll,Peter C. Thomas,S. W. Squyres,Luke Dones,Carl D. Murray,Torrence V. Johnson,Joseph A.

Vasavada +23 more
TL;DR: Findings on Jupiter's zonal winds, convective storms, low-latitude upper troposphere, polar stratosphere, and northern aurora are reported, including previously unseen emissions arising from Io and Europa in eclipse, and a giant volcanic plume over Io's north pole are described.
Journal ArticleDOI
Clouds, aerosols, and photochemistry in the Jovian atmosphere
TL;DR: In this paper, the development status of concepts for cloud and aerosol compositions, vertical and horizontal distributions, and microphysical properties, in the Jovian upper troposphere and stratosphere are assessed.
Journal ArticleDOI
HST imaging of atmospheric phenomena created by the impact of Comet Shoemaker-Levy 9
Heidi B. Hammel,Reta Beebe,Andrew P. Ingersoll,Glenn S. Orton,J. R. Mills,Amy Simon,Paul W. Chodas,John Clarke,E. De Jong,Timothy E. Dowling,Joseph Harrington,Lyle Huber,Erich Karkoschka,Charles Santori,Anthony D. Toigo,Donald K. Yeomans,Robert A. West +16 more
TL;DR: Hubble Space Telescope (HST) images reveal major atmospheric changes created by the collision of comet Shoemaker-Levy 9 with Jupiter and record the overall change in Jupiter's appearance as a result of the bombardment.
