Modeling Earth’s near-space environment and its electrical currents is challenging. A new study compares how four different models stack up against observations.
After geomagnetic storms, Earth’s corona abruptly increases in hydrogen density. For the first time, serendipitous observations have allowed researchers to investigate why.
A new method allows researchers to precisely track in three dimensions bits of fragmented magma as they are expelled in explosive volcanic eruptions.
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.
A review of the literature shows that weather nearer Earth's surface could produce up to 35% of the ionosphere's variability.
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.
Variations in Earth’s magnetic field can induce electric fields in the ground, driving damaging currents through our power grids.
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 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.
Researchers use electrical resistivity to find the heat source and reservoir feeding Long Valley Caldera's labyrinthine hydrothermal system.
