Registration Date 05-01-2023 Organization Institute of Ionosphere popup.description2  Coordinated experimental campaigns were conducted using ionosondes located in Ukraine, at the Ukrainian Antarctic Station and at the EISCAT observatory. The mentioned joint observations were carried out near the vernal equinox (March 21 – 23, 2022), as well as under magnetically quiet conditions and during a geospace storm on October 22 – 24, 2022. A comparative analysis of regular, aperiodic, and wave processes occurring at high and middle latitudes, in the northern and southern hemispheres aiming to clarify the latitudinal and longitudinal variations and establish the relationship and mutual influence of these processes under different space weather states. The results of research work can be used in fundamental studies of solar-terrestrial connections and the near-Earth environment, as well as for solving applied problems accounting the impact of non-stationary processes in the atmosphere and ionosphere on telecommunication systems, the operation of satellite equipment in the space, as well as the accuracy of geo-positioning systems.
