Artificial periodic irregularities and investigations of sporadic e-layers

Abstract

© 2019 URSI. All rights reserved. Artificial periodic irregularities (API) formed in the antinodes of the high-power standing radio wave in the Earth’s ionosphere are proven to be a powerful tool for studying E-region sporadic ionization (Es). We present some applications of the API technique for experimental studies of the Es-layer formations and parameters, and vertical motions in the lower ionosphere. We discuss too our studies of effects of the high-power radio wave pumping on the parameters of sporadic ionization that include a modification of a patchy-type Es-layer and an ionosphere diagnostics by the API technique. All experiments were carried out at the SURA heating facility (56.1 N, 46.1 E).
