Simultaneous in situ and ground-based common-volume measurements for the investigation of the formation mechanism of Polar Mesosphere Winter Echoes

Universität Rostock, 2021

Abstract: Relatively strong radar returns from mesospheric heights (~55–85 km) in the winter polar region result from coherent structures of electrons and are called Polar Mesosphere Winter Echoes (PMWE). The formation mechanism of this phenomenon is not understood. All relevant parameters potentially involved in the PMWE formation were measured in a common volume and subsequently analyzed. The combined results of rocket-borne and ground-based measurements of two rocket flights conclusively show that coherent structures are created by a turbulent process involving tiny charged meteor smoke particles.
