Thermosphere-Ionosphere Coupling

This subject area is devoted to the quantification of solar contributions (EUV, solar wind) and the influence of the lower and middle atmosphere (waves and tides) on the variability of the upper atmosphere, the interaction between ionospheric plasma and neutral gas, E- and F-region ionospheric currents from high to low latitudes, understanding and predicting ionospheric and atmospheric irregularities from equatorial to polar latitudes including signal disturbances for communication and navigation systems.
