Exploring the mismatch between modeled and observed Antarctic sea ice area
This paper helps to show that ice shelf melting is important in the ability of climate models to simulate the positive Antarctic sea ice trends. The authors perform a series of modeling experiments to simulate the effect of freshwater input from Antarctic ice shelves on the modeled trend of sea-ice extent. They find that forcing the circum-Antarctic ocean with a linearly increasing rate of freshwater input can reverse the modeled negative trend in sea-ice extent, a scenario that current Earth System Models struggle to reproduce. They also find that accounting for the latent heat required to melt the ice shelves by the ocean leads to a more positive trend in the modeled sea-ice extent.

Featured Special Collection
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.
