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 ...

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 ...

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) ...

The first global simulation study of equatorial spread F (ESF) bubble evolution using a comprehensive 3-D ionosphere model, SAMI3, has been demonstrated. The model self-consistently solves for the ...

At Earth, the ionosphere is known to supply substantial plasma to the magnetosphere, especially during geomagnetic storms. This outflow plays a critical role in shaping magnetospheric dynamics. In ...

The ionospheric D-region, spanning approximately 60–95 km above Earth’s surface, is a dynamic boundary where complex photochemical processes influence radio wave propagation. Solar flares, through ...

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 ...

WASHINGTON -- The first global simulation study of equatorial spread F (ESF) bubble evolution using a comprehensive 3D ionosphere model, SAMI3, has been demonstrated. The model self-consistently ...
