Electron density depletion: A case study

Abstract

This paper reviews what is known from other studies about electron density depletion regions found in polar regions and discusses about the different factors that can contribute to the formation of these structures. Using specific data from the EISCAT Svalbard radar, located around 78◦N, extended in different seasons of 2007, it has been confirmed most of the statistical observations of other studies from longer periods of time and a possible relation between the occurrence of depletions and some of the solar wind parameters has been found. Due to the lack of available data, not enough statistical data treatment has been done to reinforce the formulated hypothesis, therefore, future studies should be able to manage bigger amount of data
