Is Space Weather Worse by the Sea?

by Michael A. Hapgood 29 June 202028 March 2023

A new simulation of space-weather driven geoelectric fields at the land/sea conductivity boundary shows how these fields are magnified by both coastal effects and inhomogeneous land conductivity.

Globally Variable Water Content in the Mantle Transition Zone

by S. D. Jacobsen 9 June 202022 September 2022

Using electromagnetic waves originating in the ionosphere and magnetosphere, conductivity profiles reaching the deep upper mantle show surprising variability in water content.

Charging Thunderclouds Affect Ionospheric Conductivity

by David Shultz 6 September 20196 March 2023

As thunderstorm updrafts strengthen, electrification of clouds can heat the lower ionosphere, explaining prolonged disturbances to radio waves in the rarefied atmospheric layer.

Holistic Views of the Nighttime Ionosphere

by M. Liemohn 22 July 201922 March 2023

The nightside ionosphere, at latitudes away from the auroral zone, should have very little charged particle density, but it doesn’t. A new comprehensive study of satellite data explains why.

New Plasma Wave Observations from Earth’s Magnetosphere

by Terri Cook 28 January 201913 October 2022

The first simultaneous observations of multiple electromagnetic wave types in Earth’s magnetosphere may inaugurate a new field of inquiry into cross-frequency wave interactions.
