6. Substorm Features in the High-Latitude Ionosphere and Magnetosphere : Multi-Instrument Observations
Sammanfattning : The space around Earth, confined in the terrestrial magnetosphere, is to some extent shielded from the Sun's solar wind plasma and magnetic field. During certain conditions, however, strong interaction can occur between the solar wind and the magnetosphere, resulting in magnetospheric activity of several forms, among which substorms and storms are the most prominent.

7. A study of the structure and dynamics of Saturn's inner plasma disk
Sammanfattning : This thesis presents a study of the inner plasma disk of Saturn. The results are derived from measurements by the instruments on board the Cassini spacecraft, mainly the Cassini Langmuir probe (LP), which has been in orbit around Saturn since 2004. LÄS MER
8. Satellite observations of auroral acceleration processes
Sammanfattning : Measurements with satellite and sounding rocket borne instruments contain important information on remote and local processes in regions containing matter in the plasma state. The characteristic features of the particle distributions can be used to explain the morphology and dynamics of the different plasma populations. LÄS MER
9. Auroral and meteor applications of the EISCAT incoherent scatter radar
Sammanfattning : .... LÄS MER
10. Design and development of a microwave multifrequency polarimetric scatterometer for biosphere remote sensing
Sammanfattning : Microwave radar and radiometer techniques are used to gather crucial information about the earth and its atmosphere. The ERS-1, JERS-1, RadarSAT and NASA’s Mission to Planet Earth projects are designed to study the changing global environment. In all these endeavors, the key instrument is the radar or scatterometer. LÄS MER
