3D printing gives new insights into the falling behavior of atmospheric ice particles

Editor’s Highlight—

 

This study revisits a relatively old topic using a new technology, 3D printing. The authors use 3D-printed analogues of various ice crystal shapes to study the fall velocity dependence on shape, important for the lifetime of cirrus clouds and cloud microphysics generally. The analogues allow parameterizations of fall velocity to be further tested and refined with control over the precise shapes under consideration.

Early Results: Juno at Jupiter 

Early results from Juno's mission at Jupiter including approach to Jupiter and the first perijove pass (PJ1). Juno's scientific objectives include the study of Jupiter's interior, atmosphere and polar magnetosphere with the goal of understanding Jupiter's origin, formation and evolution. This collection of papers provides early results from Juno's measurements of the gravity and magnetic fields, deep atmospheric microwave sounding, infrared, visible and ultraviolet images/spectra and an array of fields and particles instruments as well as context for the early results with respect to current theory and models of Jupiter's formation and evolution. Topics include both Juno - Jupiter related theoretical models and data analysis as well as collaborative observations made from Earth based assets.
