  3. 2. Satellite microwave measurements of cloud ice properties

    Författare :Bengt Rydberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sub-mm; cirrus; upper troposphere; Odin; remote sensing; CloudSat; data retrieval;

    Sammanfattning : Upper tropospheric cloud ice and water vapour are two intimately connected components of the atmosphere, that influence the Earth's energy budget. The response of these components to a warming climate is not well understood. LÄS MER

  4. 3. Satellite microwave measurements of ice cloud properties

    Författare :Bengt Rydberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cirrus; radiative transfer; CIWSIR; microphysical properties; inversions; Odin;

    Sammanfattning : Ice clouds play an important role in Earth's radiation balance and climate because they reflect incoming sunlight and trap outgoing infrared radiation. There is still an uncertainty about how ice clouds will respond to the effects of global warming. Many climate models use prognostic cloud mass schemes to represent cloud feedbacks. LÄS MER

  7. 5. Analysis of Arctic ice cloud properties using in-situ and remote sensing measurements

    Författare :Veronika Wolf; Thomas Kuhn; Peter Völger; Martin Gallagher; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic cirrus clouds; ice particle properties; in-situ measurements; in-situ and lidar comparison; Atmospheric science; Atmosfärsvetenskap;

    Sammanfattning : Cirrus clouds play an important role in the radiation balance of the atmosphere as theycan have a warming and cooling effect. The resulting net radiation effect depends ontheir micro- and macrophysical properties such as particle size, shape, and numberconcentration. LÄS MER
