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 ...

This report summarises the existing state of knowledge of the influence of the ionosphere upon medium-wave broadcasting. After a brief discussion of the parameters determining the electrical behaviour ...

Ionospheric irregularities represent spatial and temporal variations in the electron density of the Earth’s ionosphere, which are closely interwoven with broader atmospheric dynamics. These ...

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, ...

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

Scientists at the Indian Institute of Geomagnetism have developed a new model for radio wave propagation through the ionosphere. This model can help estimate the impact of space weather and facilitate ...

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 ...
