Type 2 ionospheres start to blend with Type 1 ionospheres around index 650; if we consider this as point discriminating active and inactive ionospheres, then 69 per cent of observations lack ionospheric activity.

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 about 50 km (30 mi) to more than 1,000 km … 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 … Meer weergeven Ionograms allow deducing, via computation, the true shape of the different layers. Nonhomogeneous structure of the electron/ion-plasma produces rough echo traces, seen predominantly at night and at higher latitudes, … Meer weergeven Radio communication Due to the ability of ionized atmospheric gases to refract high frequency (HF, or shortwave) radio waves, the ionosphere can reflect … Meer weergeven Webionospheres of Mars and Venus J.-S.

WebIonospheres provides a comprehensive description of the physical, plasma and chemical processes controlling the behavior of ionospheres. The relevant transport equations and related coefficients are derived in detail and their applicability and limitations are described. Relevant wave processes are outlined and important ion chemical processes and … WebAbstract: We report the results of measurements obtained in conjunction with a series of high-altitude chemical release experiments of effects of artificially modified ionospheres upon high-frequency, ionospherically reflected radio paths. Computer simulations indicate that under optimum conditions, ionospheric modifications induced by chemical releases … Web0521607701 - Ionospheres: Physics, Plasma Physics, and Chemistry Robert W.
