  2. 1. Low-Energy Ion Escape from the Terrestrial Polar Regions

    Author : Erik Engwall; Anders I. Eriksson; Mats André; Thomas Moore; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; space physics; ion outflow; polar wind; auroral upflows; atmospheric escape; magnetotail lobes; spacecraft wake; electric field measurements; Geocosmophysics and plasma physics; Geokosmofysik och plasmafysik; Space and Plasma Physics; rymd- och plasmafysik;

    Abstract : The contemporary terrestrial atmosphere loses matter at a rate of around 100,000 tons per year. A major fraction of the net mass loss is constituted by ions, mainly H+ and O+, which escape from the Earth’s ionosphere in the polar regions. READ MORE

  4. 2. O+ outflow during geomagnetic storms observed by Cluster satellites

    Author : Audrey Schillings; Hans Nilsson; Stephan Buchert; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmosfärsvetenskap; Atmospheric Science;

    Abstract : The region of space dominated by the Sun's magnetic field is called the heliosphere. It envelops the entire solar system including Earth. Therefore, a strong coupling exists between the Sun and our planet. READ MORE

  5. 3. How does O+ outflow vary with solar wind conditions?

    Author : Audrey Schillings; Hans Nilsson; Rikard Slapak; Lars-Göran Westerberg; Christopher Cully; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmosfärsvetenskap; Atmospheric science;

    Abstract : The entire solar system including Earth is enveloped in a region of space where the Sun’s magnetic field dominates, this region is called the heliosphere. Due to this position in the heliosphere, a strong coupling exists between the Sun and our planet. READ MORE

  6. 4. Energization and Acceleration of Dayside Polar Outflowing Oxygen

    Author : Sachiko Arvelius; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solar wind-magnetosphere interactions; Magnetosphere-ionosphere coupling; O energization acceleration; O outflow; Space physics; Rymdfysik;

    Abstract : This thesis deals with energetic oxygen ions (i.e. single-charged atomic oxygen ions, O+) at altitudes higher than 5 Earth radii (RE) and at latitudes above 75 (toward 90) degrees invariant latitude (deg ILAT) in the dayside polar magnetosphere observed by Cluster. READ MORE

  7. 5. O+ heating, outflow and escape in the high altitude cusp and mantle

    Author : Rikard Slapak; Andrew Yau; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Abstract : The Earth and its atmosphere are embedded in the magnetosphere, a region in space dominated by the geomagnetic field, shielding our planet as it acts to deflect the energetic solar wind. Even though the atmosphere is protected from direct interaction with the solar wind it is indirectly affected by significant magnetosphere-solar wind interaction processes, causing constituents of the upper atmosphere to flow up into the magnetosphere.
