On the relation between type-II ion outflow and naturally enhanced ion acoustic lines in the polar ionosphere
Di Loreto, Massimo (Master thesis; Mastergradsoppgave, 2013-11-15)In this work we investigated the relation between type-II ion outflows and NEIALs. Currently, several ion outflows acceleration mechanisms and NEIALs generation theories have been proposed. In the first part of this thesis we review the most important works regarding these two processes. In the second part we present the results of our analysis, together with some unexpected events which were not ... -
Revisiting geomagnetic activity at auroral latitudes: No need for regular quiet curve removal for geomagnetic activity indices based on hourly data
Martini, Dániel; Argese, Chiara; Di Loreto, Massimo; Mursula, K. (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-06-24)The main objective of our study is to determine if the regular quiet daily curve (QDC) subtraction is a necessary procedure in quantifying the irregular geomagnetic variations at auroral latitudes. We define the hourly ΔH index, the absolute hour-to-hour deviation in nT of the hourly geomagnetic horizontal component, which assigns each sample to sample deviation as geomagnetic activity without ...
