  1. 1. Implementing Total Electron Content in the Grand Unifed Incoherent Scattering Design and Analysis Program for Investigation of Causes to Scintillations

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Samuel Sonesson; [2023]
    Keywords : Total Electron Content; Scintillation; Incoherent Scattering; Ionosphere;

    Abstract : Functionality for calculating and plotting diferent Total Electron Content (TEC) measurements such as Slant Total Electron Content (sTEC), error in sTEC, and VerticalTotal Electron Content (vTEC) was implemented into the data analysis program fromEuropean Incoherent Scattering Scientifc Association (EISCAT), the Grand Unifed Incoherent Scattering Design and Analysis Program (GUISDAP). This utilises a thin-singlelayer model of the ionosphere to convert sTEC into the more analytically useful vTEC. READ MORE

  3. 2. Validating and comparing Total Electron Content estimates from Incoherent Scatter Radar and Global Positioning System

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Sven Molenkamp; [2023]
    Keywords : ;

    Abstract : This thesis aims to analyze the possibilities to use Incoherent Scatter Radar to measure Total Electron Content in the ionosphere. By comparing the results from EISCATselectron density data over altitude and time to Total Electron Content estimates from GPS satellites and their receivers through a climatology as well as qualitative analysis for separate EISCAT experiments a comparison between the two is conducted.

  4. 3. 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)

    Author : Anton Thorell; [2023]
    Keywords : Sporadic-E layers; plasma physics; space physics; arctic geophysics; radar technology; UNIS; Svalbard; EISCAT.; Sporadiska E-skikt; plasmafysik; rymdfysik; arktisk geofysik; radarteknik; UNIS; Svalbard; EISCAT.;

    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

  5. 4. Atmospheric Gravity Waves revisited with the EISCAT radar

    University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen; Uppsala universitet/Institutionen för fysik och astronomi

    Author : Tatsuya Hirabayashi; [2023]
    Keywords : ;

    Abstract : It is known that AGWs strongly interact with Traveling Ionospheric Disturbancescalled TIDs (e.g. Kirchengast et al., 1996). READ MORE

  6. 5. On the Relationship Between Energetic Electron Precipitation and Mesopause Temperature

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Florine Enengl; [2019]
    Keywords : ;

    Abstract : Energetic Particle Precipitation (EPP) can potentially change the neutral atmospheric temperatureat the mesopause region. Cresswell-Moorcock et al. (2013) used European IncoherentScatter Scientific Association (EISCAT) radar data to identify strong electron precipitationevents. READ MORE
