Earth's ionosphere, reference models. The ionosphere is the ionised part of the Earth's atmosphere, reaching from around 60 to 1000 kilometres above the Earth's surface. This image shows three different models used to represent aspects of the ionosphere. The orange loops represent the low-latitude parts of the Earth's geomagnetic field, which affects the motion of ions in the atmosphere. The horizontal winds are shown at two altitudes: 350 kilometres (purple arrows) and 100 kilometres (white arrows). Oxygen ion density is shown at an altitude of 350 kilometres, and is colour coded from blue (low values) through green, yellow and orange to red (high values). The ionisation is caused by the Sun, and studying the ionosphere is a key part of understanding the effect space weather has on satellite communications and related technology. | |
