Are Humans to Blame for Worsening Heat Waves in China?
From Eos.org: Research Spotlights— A new study suggests that even hotter events will follow unless greenhouse gas emissions are reduced. At least 40 people died during China’s record-breaking 2013 heat wave, when temperatures spiked to more than 105°F. The deadly event was just one of a string of.... more
Two ice core records reconstruct paleoclimate in North Pacific
Editor’s Highlight— This paper presents a long-term record of sea salt accumulation in the Denali ice core from Alaska, which is interpreted as a time series of the strength of the wintertime Aleutian Low pressure system. The main conclusions are that the strength of the Aleutian Low has been increasing.... more
Insights into the journeys of aerosol particles over the Arctic
Editor’s Highlight— Arctic boundary layer clouds play an important role in the surface energy balance. Given the often-pristine conditions, the optical and microphysical properties of these clouds are sensitive to the number concentration of aerosol particles that can act as cloud condensation nuclei.... more
How Quickly Is Mercury’s Surface Evolving?
From Eos.org: Research Spotlights— New measurements of impact craters on Mercury’s smooth plains suggest the topography of the solar system’s innermost planet is changing at twice the rate of landforms on the Moon. For the last several billion years, collisions with meteoroids, asteroids, and comets.... more
Reconciling the deformational dichotomy of the 2016 Mw 7.8 Kaikoura New Zealand earthquake
Commentary in Geophysical Research Letters Following the 2016 Mw 7.8 Kaikoura earthquake, uncertainty over the nature of the coseismic rupture developed. Seismological evidence pointed to significant involvement of the subduction megathrust, while geodetic and field observations pointed to a shallow.... more
A challenge to the longstanding theory on auroral arc formation
Editor’s Highlight— The ionospheric feedback instability (IFI) has been postulated for many years since the seminal paper by Atkinson in 1970. This paper is the first work that applies a simplified height-resolved ionosphere, and it shows a very real problem with previous studies on this instability.... more
Warm winter events in the Arctic are becoming more frequent, lasting longer
Press Release— Arctic winter warming events – winter days when temperatures peak above minus 10 degrees Celsius – are a normal part of the Arctic climate over the ice-covered Arctic Ocean, but new research finds they are becoming more frequent and lasting longer than they did three decades ago. A new.... more
Huge Storms Disrupted Jupiter’s Fastest Jet Stream in 2016
From Eos.org: Research Spotlights— Recurrent jet stream disturbances provide glimpses of what lies beneath the gas giant’s thick upper cloud cover. In late 2016, a quartet of huge storms disrupted the usually stable flow of a rapid atmospheric jet stream that encircles Jupiter. Multiple instruments.... more
Greenland’s summer ocean bloom likely fueled by iron
Blog— Iron particles catching a ride on glacial meltwater washed out to sea by drifting currents is likely fueling a recently discovered summer algal bloom off the southern coast of Greenland, a new study finds. Microalgae, also known as phytoplankton, are plant-like, marine microorganisms that form.... more
Global analysis of ocean float data reveals particulate concentrations at depth
Editor’s Highlight— A global array of Argo floats equipped with bio-optical sensors presents an opportunity for a large-scale study of the subsurface variability of various biogeochemical parameters that has not been possible before. The authors analyzed data from almost 250 floats producing over.... more

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.
