1. Sporadic-E layers in the polar cap ionosphere : A review on Es occurrence, dynamics and formation theory
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Sporadic-E layers (Es) are layers of metallic ions that appear in the lower E-region of the ionosphere and can last from under one hour to several hours. Es are found at all latitudes, but polar cap Es, and specifically over Svalbard at a latitude of around 78◦ , are the focus of this study. READ MORE
