    Optical auroral research: Faster, higher, fainter!
    Radio induced optical emissions: We can make our own aurora!

    Main research area: Combined optical and incoherent scatter radar
    (ISR) observations of aurora and HF-radio wave enhanced optical
    emissions. The work on aurora ranges from observations and analysis of
    intensified high-speed (25-50 frames per second) white light video
    recording with the Odin imager (http://www.phys.uit.no/~maarten/of
    "flickering aurora" (where the intensity varies at frequencies up to
    15 Hz) and "black aurora" (narrow structures with reduced luminosity
    in diffuse aurora), to tomography-like estimates of the
    three-dimensional distribution of auroral volume emission rates using
    image data from the Auroral Large Imaging System
    (http://www.alis.irf.se/) and other multi-station optical
    observations. When such observations are combined with ionospheric
    parameters from ISR observations it is possible to discriminate
    between proposed theoretical explanations. In particular this is
    possible with HF-Heating experiment where the ionosphere is modified
    with a high-frequency (~4-8 MHz) radio-wave beam that heats the
    ionospheric electrons (from 1000 to 3500 K), creates small-scale
    (~10 m) density depletions, drive wave-wave processes that causes the
    ionosphere to emit radio waves, and accelerates electrons to high
    energies enough to excite thermospheric atoms that emit visible
    light. The possibility to control the HF-pump wave (its frequency,
    light. The possibility to control the HF-pump wave (its frequency,
    power, polarization, direction, pump-cycle duration, etc) makes it
    possible to test theories for wave-plasma interaction.
