Testing Models of Near-Space Electrical Currents

by L. Crane 18 July 201716 November 2021

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

How Geomagnetic Storms Light Up the Geocorona

by L. Crane 14 July 201713 April 2022

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

Tracking Volcanic Bombs in Three Dimensions

by L. Crane 13 March 20172 May 2022

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

Polar Interlopers in the Aurora

by L. Crane 9 March 201716 November 2021

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.

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

When Lower-Atmosphere Waves Invade the Upper Atmosphere

by L. Crane 28 February 201719 October 2021

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

Reading Raindrops: Microphysics in Typhoon Matmo

by L. Crane 9 December 20163 February 2022

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.

Mapping Geoelectric Hazards Across the United States

by L. Crane 13 October 20165 July 2022

Variations in Earth’s magnetic field can induce electric fields in the ground, driving damaging currents through our power grids.

Earthquakes Could Funnel Radio Waves to Dark Zones in Mountains

by L. Crane 29 September 20167 October 2021

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

by L. Crane 29 September 20161 November 2021

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.
