Satellite signals can be used to map the electron content of the ionosphere, the part of Earth’s upper atmosphere in which some atoms and molecules become ionized.

Researchers mapped Earth’s ionosphere, part of the upper atmosphere, using signal data from 40 million phones – a method that could improve GPS accuracy and help track space weather ...

For the first time, researchers have used real-time data from around 40 million mobile phones to map conditions in the ionosphere — a region of the upper atmosphere in which some of the air ...

The Earth’s atmosphere has a number of layers. The region we know best, because it is where our weather happens, is the troposphere. This dense blanket of air 5 to 9 miles thick contains 80 ...

Anton Petrus/Getty Images. Satellite communication technology is gaining global attention as its signals expand beyond the Earth's surface and to the upper atmosphere and space.

Satellite SOS allows users to connect to the only other option when Wi-Fi and mobile data aren’t available – a network of satellites almost always flying through the upper atmosphere above ...

What is upper atmospheric cooling? Upper atmospheric cooling is the phenomenon in which, "while the blanket of air close to the Earth's surface is warming, most of the atmosphere above is becoming ...

“Limb-sounding remote sensing represents an innovative approach in space-based atmospheric observation. This technique involves positioning a satellite at a specific orbital altitude, where it ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Scientists have now used Japan's extensive network of ...
