  1. 6. Bird's eye view of star formation in the local Milky Way - How perspective changes with scale, time and viewing angle

    Författare :Andri Spilker; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; interstellar medium; star formation;

    Sammanfattning : A crucial aspect in interpreting the scaling relations relevant for star formation—the Kennicutt-Schmidt relation and the Larson relations—is how those relations depend on size-scale. This is especially so when comparing relations derived from unresolved, extragalactic data to those derived from resolved, Galactic data. LÄS MER

  3. 7. Synthetic-Aperture Radar Imaging of Forests in the VHF and UHF Bands: Electromagnetic Models and Data Analysis

    Författare :Björn Hallberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image formation; biomass mapping; Synthetic-aperture radar SAR ; ionospheric propagation; electromagnetic models; forest monitoring; remote sensing;

    Sammanfattning : Synthetic-aperture radar (SAR) is a technique which can image the Earth’s surface, from a spaceborne or airborne platform, irrespective of daylight or cloud cover. During the last decades there has been an increasing interest in using SAR for estimation of forest parameters. LÄS MER

  4. 8. Modelling the middle atmosphere and its sensitivity to climate change

    Författare :Andreas Jonsson; Jörg Gumbel; Joanna Haigh; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate change; middle atmosphere; ozone; carbon dioxide; stratosphere; mesosphere; chemical kinetics; atmospheric tides; Meteorology; Meteorologi;

    Sammanfattning : The Earth's middle atmosphere at about 10-100 km has shown a substantial sensitivity to human activities. First, the ozone layer has been reduced since the the early 1980s due to man-made emissions of halogenated hydrocarbons. LÄS MER
