A Comparison of Naturally Enhanced Ion Acoustic Lines and Auroral Spectral Line Emissions
Hansen, Rikke Hedelund (Master thesis; Mastergradsoppgave, 2019-05-31)In this thesis, we present Naturally Enhanced Ion Acoustic Lines (NEIALs) observed with the EISCAT Svalbard Radar and a comparison with auroral emissions lines measured with a Meridian Scanning Photometer. NEIALs are short-lived events noticeable in the incoherent scatter spectra as an enhancement in one or both shoulders. It has been assumed that NEIALs are associated with an active red emission ...
