The ionosphere is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation. It plays an important role in atmospheric … Meer weergeven As early as 1839, the German mathematician and physicist Carl Friedrich Gauss postulated that an electrically conducting region of the atmosphere could account for observed variations of Earth's magnetic … Meer weergeven An ionospheric model is a mathematical description of the ionosphere as a function of location, altitude, day of year, phase of the sunspot cycle and geomagnetic activity. … Meer weergeven X-rays: sudden ionospheric disturbances (SID) When the Sun is active, strong solar flares can occur that hit the sunlit side of Earth with hard X … Meer weergeven The ionosphere is a shell of electrons and electrically charged atoms and molecules that surrounds the Earth, stretching from a height of … Meer weergeven At night the F layer is the only layer of significant ionization present, while the ionization in the E and D layers is extremely low. During the day, the D and E layers become much more heavily ionized, as does the F layer, which develops an … Meer weergeven Ionograms allow deducing, via computation, the true shape of the different layers.
