Testing Models of Near-Space Electrical Currents

Modeling Earth’s near-space environment and its electrical currents is challenging. A new study compares how four different models stack up against observations.

Atmospheric Sciences

New research unveils how geomagnetic storms influence Earth’s geocorona

Research Spotlight 14 July 2017

How Geomagnetic Storms Light Up the Geocorona

After geomagnetic storms, Earth’s corona abruptly increases in hydrogen density. For the first time, serendipitous observations have allowed researchers to investigate why.

Mathematical Geophysics

Researchers work to track the fragmented magma bombs that fly through the air during an explosive eruption

Research Spotlight 13 March 2017

Tracking Volcanic Bombs in Three Dimensions

A new method allows researchers to precisely track in three dimensions bits of fragmented magma as they are expelled in explosive volcanic eruptions.

Researchers spot the cause of poleward boundary intensifications in Earth’s aurora

Research Spotlight 9 March 2017

Polar Interlopers in the Aurora

A new study suggests that poleward boundary intensifications in the aurora are caused by fast flows of plasma from the poles into the auroral oval.

Space Science & Space Physics

Researchers track how weather close to Earth’s surface influences the ionosphere.

Research Spotlight 28 February 2017

When Lower-Atmosphere Waves Invade the Upper Atmosphere

A review of the literature shows that weather nearer Earth's surface could produce up to 35% of the ionosphere's variability.

Atmospheric Sciences

Researchers analyze the small physical processes in Typhoon Matmo

Research Spotlight 9 December 2016

Reading Raindrops: Microphysics in Typhoon Matmo

Quantitative predictions about tropical storms require an understanding of even their smallest physical processes. A new study observes unusual microphysics in 2014's Typhoon Matmo.

Earthquakes Could Funnel Radio Waves to Dark Zones in Mountains

By being coupled with a layer of mobile electrical charges on the Earth's surface, radio waves could travel over the ground to areas that would normally be unreachable, like behind a mountain.

Tide Gauge Records May Underestimate 20th Century Sea Level Rise

Tide gauges can help measure sea level change, but their limited locations and short records make it hard to pinpoint trends. Now researchers are evaluating the instruments' limitations.
