    Sammanfattning : We have studied fundamental aspects of time-resolved two-photon excited fluorescence depolarisation. The thesis presents experimental as well as theoretical progress. LÄS MER

  3. 2. Modelling optical properties of morphologically complex soot aerosols

    Författare :Franz Kanngiesser; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aerosol; remote sensing; depolarisation; lidar; black carbon; scattering;

    Sammanfattning : Soot containing aerosol has both adverse impacts on the Earth's climate and on human health. Monitoring soot sources, transport pathways and sinks on global scale requires satellite-borne remote sensing techniques. LÄS MER

  4. 3. Modelling optical properties of morphologically complex aerosols

    Författare :Franz Kanngiesser; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; remote sensing; sea salt; black carbon; aerosol; scattering; mineral dust.; depolarisation;

    Sammanfattning : The interpretation of remote sensing data of atmospheric aerosol particles requires a thorough understanding of the links between microphysical and optical properties. Morphologically complex aerosol models describe the particles’ morphology in detail. LÄS MER
