Tropospheric Influence on the Ionosphere in Mid-latitudes
Original language description
The ionosphere is highly variable atmospheric plasma influenced from below and from above. The most important factors that affect ionosphere are related solar and geomagnetic activity (e.g. solar irradiation, solar wind coupling, through the magnetosphere). Ionosphere reflects external forcing in variability on scales from minutes to a solar cycle. However, the influence of the lower atmosphere through thermospheric chemistry and dynamics cannot be neglected because the number of neutrals highly exceeds the ionized particles by several orders of magnitude. Processes in the lower laying atmosphere such as UV radiation absorption by the stratospheric ozone, severe meteorological formations in the troposphere, and/or generation of wide range of atmospheric waves by the orography, earthquakes, waves related to human activity and other sources, play an important role in the ionospheric behavior. As the atmospheric waves propagate upward from the source region, their energy tends to be conserved and consequently the amplitude grows due to the decreasing atmospheric density. Despite the fact that most of the atmospheric waves do not reach higher heights than mesosphere and lower thermosphere an important portion of nthe atmospheric waves penetrate up to the ionosphere-thermosphere system, nwhich has been proven experimentally. Signatures of the wave-like oscillation within ionospheric plasma are detected by mean of vertical sounding data (electron density and plasma drift). The data are joined with stratospheric measurements and tropospheric observations to demonstrate the atmospheric vertical influence.
