The ionosphere plays a critical role in radio communications and space weather prediction, and its dynamic behaviour is often monitored through ionograms. These graphical records provide insights into ...

The ionosphere -- the region of geospace spanning from 60 to 1000 kilometers above the Earth -- impairs the propagation of radio signals from global navigation satellite systems (GNSS) with its ...

Ionospheric anomalies, such as increased electron density, lowered ionospheric altitude, and slowed abnormal propagation of medium-scale traveling ionospheric disturbances, have been repeatedly ...

The subsurface of Mars records important historical information on the formation and evolution of Mars. As an ionized medium, the Martian ionosphere plays a special role in radio wave propagation and ...

For all the successes of modern weather forecasting, where hurricanes, blizzards, and even notoriously unpredictable tornadoes are routinely detected before they strike, reliably predicting one aspect ...

IOWA CITY -- Late last month, a NASA sounding rocket carrying a University of Iowa instrument – along with others – made an evening foray nearly 100 miles straight up into the Earth’s ionosphere, ...

On November 8th, 2020 the Sun exploded. Well, that’s a bit dramatic (it explodes a lot) — but a particularly large sunspot named AR2781 produced a C5-class solar flare which is a medium-sized ...

Electron density of the Ionosphere around the Earth for a certain point of time: high values in red, low values in blue. The white line marks the geomagnetic equator ...

With the help of neural networks, the complexity of the layer around the Earth can be reconstructed much better than before. This is important for satellite navigation, among other things. The ...
