Dense GNSS networks enable scientists to track large-scale waves traveling through the upper atmosphere, away from sources in the auroral zone and the day/night terminator.
Scintillation—flickers and distortions in radio waves passing through the ionosphere—can happen during daytime and at much lower dip latitudes than previously thought.
Exploring the relationship between solar extreme ultraviolet radiation flux and 150-km radar echoes.
Using data from the European Space Agency's Swarm mission, scientists find that abrupt drops in the ionosphere's electron density may cause low-orbiting satellites to lose contact with GPS satellites
Scientists studying a 50–year–old mystery in the Earth's ionosphere have come up with their best explanation of it yet.
