Impact of the lower thermospheric winter-to-summer residual circulation on thermospheric composition

Editor’s Highlight—

 

This study suggests the significance of “residual thermospheric circulation,” a process acting like a “lower thermospheric spoon,” that was long neglected but could be responsible for the seasonal gradients in the thermosphere and ionosphere and account for a long-standing deficiency in models for circulation in the upper atmosphere. Through a set of simulations, the authors investigate the significance of the process of residual thermospheric circulation, and conclude that it is important in representing seasonal gradients in the thermosphere and ionosphere.

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.
