A GEOPHYSICAL Discussion dealing with the ionosphere was held in the rooms of the Royal Astronomical Society on May 31, with Prof. S. Chapman in the chair.

Progress of waves through open sea sends vibrations that magnify with height up the entire atmospheric column. The signals of GPS satellites could be used to monitor tsunamis as they sweep across ...

The Ionosphere Above the stratosphere the sparse atoms and molecules of air are disrupted by the harsher radiations of the sun. A revealing and useful property of this mantle is its reflection of ...

The ionosphere’s reaction to happenings on the ground is simple in principle but complex in practice. Events like earthquakes produce disturbances in the lower atmosphere.

Scientists studying the zone between Earth’s atmosphere and space spotted unusual X- and C-shaped features that could thwart signals that keep our planet running smoothly.

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 ...

The "Ionosphere Monitoring and Prediction Center" (IMPC) developed and operated by DLR provides a near real-time information and data service on the current state of the ionosphere, related forecasts ...

The ionosphere has many fascinating characteristics. Near the Earth’s surface, you don’t find many electrically charged particles, Maruca said. But the higher you go, the more you find. The ionosphere ...

Better coverage This map shows the locations of the 9036 monitoring stations (orange dots) that are used to observe the ionosphere. The orange dots overlay blue dots, which show approximately 100,000 ...

The ionosphere consists of three major layers, known as D, E and F layers. The lower D and E layers typically exist only during daylight hours, while the highest F layer always exists. These ...

Analogous approaches are found in ocean-atmosphere coupled data assimilation. We have examined the impact of assimilating GNSS-based plasma density observations, from radio occultation experiments as ...
