4. 2. Auroral Electric Fields From Satellite Observations and Numerical Modelling

   Author : Tomas Karlsson; KTH; []
   Keywords : Satellite measurements; electric fields; ionosphere; magnetosphere; diverging electric fields; downward current region; black aurora; westward travelling surge; auroral bulge; subauroral ion drifts SAID ; subauroral electric fields SAEF ; mid-latit; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : This thesis is about electrodynamics of thehigh-latitude/auroral region of near-Earth space. The work ismainly based on electric field measurements made by the doubleprobe instrument on the Freja satellite at altitudes ofapproximately 800-1700 km, together with measurements fromother instruments on the same satellite, and ground-basedinstrumentation.

5. 3. Satellite observations of auroral acceleration processes

   Author : Lars Eliasson; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aurora; particle acceleration; space plasma; magnetosphere; ionosphere; polar cap; satellite observations;

   Abstract : 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. READ MORE

6. 4. Global Magnetospheric Plasma Convection

   Author : Stefan Eriksson; KTH; []
   Keywords : Geophysics; satellite measurements; electric fields; magnetosphere; magnetic reconnection;

   Abstract : This thesis deals with the global aspects of plasmaconvection in the magnetosphere as measured by the low-altitudepolar orbiting Astrid-2 and FAST satellites. The major focus ison the electric field measurements, but they are alsocomplemented by magnetic field, ion and electron particle data,which is fundamental for the understanding of theelectrodynamics of the high-latitude auroral ovals and polarcap, which are the regions analysed here.

7. 5. Auroral electrodynamics of plasma boundary regions

   Author : Sónia Liléo; Göran Marklund; Anders Eriksson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space physics; Rymdfysik;

   Abstract : The electrodynamic coupling between the auroral ionosphere and the magnetosphere is the main subject of this thesis. Satellite measurements of electric and magnetic fields and of charged particles are used to explore three distinct plasma boundaries, magnetically linked to the nightside auroral ionosphere. READ MORE
