Пространственная структура поляризационного джета по данным спутников NORSAT-1 и SWARM
In this work, we study the spatial structure of the polarization jet based on data from the NorSat-1 and Swarm ionospheric satellites during a geomagnetic storm. A comparative analysis of the electron density and temperature dependence on the invariant latitude is carried out simultaneously according to measurements of the NorSat-1 and Swarm C satellites during their crossing of the polarization jet. The dependence of the invariant latitude of polarization jet on the auroral geomagnetic activity and on the magnetic local time is confirmed. A double structure of polarization jet is discovered as well as small-scale spatial structures inside the jet with a size of 0.1°–0.2°. It is found that spatial structures are not local and are extended in longitude for at least 2 h of magnetic local time.
