Session: Thermosphere-Ionosphere Interactions and Effects

Abstract

The ionospheric layers arise as a result of high-energy solar UV and X-ray radiation and their interaction with the Earth’s upper atmosphere. Space Weather effects can lead to ionospheric disturbances, such as scintillation, and other phenomena that can influence signal propagation between ground- and space- based systems. The dependence on much of our technological infrastructure on satellite-based communications or GNSS highlights the need for coherent systems to address the vulnerability of these systems. We will present these services provided by the ESA SSA Space Weather Service Network that provide data measurements and forecasts of TEC maps, applications to GNSS corrections, scintillation maps, other ionospheric activity parameters and disturbances that impact the transionospheric radio transmissions.
