Webmanuscript submitted to Geophysical Research Letters - 5 - 122 validated by comparing it with the zonal wind obtained from re-analysis data, empirical models, and 123 ground-based radar and lidar observations (Liu et al., 2024). The balance wind extends from 50°S to 124 50°N at z=18–100 km and can be used to study the possible mechanisms underlying the … In telecommunication and radio science, an ionospheric sounding is a technique that provides real-time data on high-frequency ionospheric-dependent radio propagation, using a basic system consisting of a synchronized transmitter and receiver. The time delay between transmission and reception is translated into effective ionospheric layer altitude. Vertical incident sounding uses a collocated transmitter and receiver and involves direc…

It is demonstrated that, with a view to the proposed average criterion, a model can be found, which utilizes … WebProcesses and threats related to natural hazards play an important role in the evolution of the Earth and in human history. The purpose of this study is to investigate magnetic field variations measured at low Earth orbit (LEO) altitudes possibly associated with earthquakes, volcanic eruptions, and artificial outbursts. We focus on two missions with well equipped … Web17 jun. 2024 · The monograph presents the study results of aperiodic and quasi-periodic wave perturbations in the ionosphere during unique phenomena in geospace: partial solar eclipses, the fall of the Chelyabinsk cosmic body and during the operation of a powerful radio source – the heating stand «Sura». popular now in ohio
