  4. 3. Use of remote sensing and in situ observations of the atmosphere in chemical transport models

    Författare :Emma Ward; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate; Air quality; Ground based observations; Satellite observations; Chemical transport modelling;

    Sammanfattning : Measuring and simulating atmospheric chemical compositions helps us to better understand the impact from long-range transport of different pollutants. Aerosols and tropospheric ozone are examples of pollutants with life times long enough to get transported between continents. LÄS MER

  5. 4. A Cross-Correlator for the Remote Sensing of Earth by Synthetic Aperture

    Författare :Erik J Ryman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cross-correlation; synthetic aperture; ASIC; VLSI.; earth observation;

    Sammanfattning : In light of our changing climate and the unpredictability of severe weather; a better understanding of our climate and increased weather forecast accuracy are in high demand. Humidity and temperature distribution profiles with high temporal resolution can significantly increase our knowledge of highly dynamic weather phenomena and improve weather forecasts. LÄS MER

  7. 5. Towards an improved understanding of precipitation variations over the Tibetan Plateau

    Författare :Hui-Wen Lai; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Third Pole; Tibetan Plateau; precipitation; Asian summer monsoon; westerly jets; Regional Climate Model; satellite observation;

    Sammanfattning : The Tibetan Plateau (TP) and surrounding regions are known as the ``Third Pole'' because of their polar-like environment and large reservoirs of fresh water. Due to the latter aspect, the TP is also considered the ``Water Tower of Asia'', providing essential water resources to the surrounding regions. LÄS MER
