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 ...

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 ...

Radio broadcasters compete for airwave space in the saturated FM range, in detriment to AM wavebands with a poorer sound quality. Nevertheless, frequencies at wavebands less than 30 MHz (AM ones) ...

Tropical cyclones, with their intense convective systems and dynamic atmospheric circulations, have been shown to impact the ionosphere significantly. These large-scale weather systems generate ...

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, ...

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 ...

The eclipse across America on Aug. 21 was not only a magnificent visual event, it was also observed indirectly by the impact that it had on the propagation of radio signals — including those of global ...

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 ...
