  2. 6. Satellite microwave measurements of cloud ice properties

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

    Abstract : 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. READ MORE

  4. 7. Satellite microwave measurements of ice cloud properties

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

    Abstract : 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. READ MORE

  5. 8. Satellite observations of auroral acceleration processes

    Author : Lars Eliasson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aurora; particle acceleration; space plasma; magnetosphere; ionosphere; polar cap; satellite observations;

    Abstract : Measurements with satellite and sounding rocket borne instruments contain important information on remote and local processes in regions containing matter in the plasma state. The characteristic features of the particle distributions can be used to explain the morphology and dynamics of the different plasma populations. READ MORE

  6. 9. On the use of aerosol optical properties and satellite-retrieved trace gases in regional air quality modelling

    Author : Emma Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Model; Climate; Radiation; Satellite; Air Quality;

    Abstract : The effects of anthropogenic pollutants in the lower atmosphere (troposphere) have been shown, historically and scientifically, to have a deleterious effect on both plant and animal life. Pollutants such as near-surface ozone and soot (black carbon) are two notorious examples with clear anthropogenic sources. READ MORE

  7. 10. Multi-satellite views on mesospheric microphysics and dynamics

    Author : Lina Broman; Jörg Gumbel; Susanne Benze; Scott Bailey; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polar mesospheric clouds; satellite tomography; remote sensing; cloud microphysics; wave dynamics; mesosphere; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Atmospheric gravity waves of different scales and origins strongly modulate the wind field and temperature structure of the higher parts of the atmosphere. Direct and continuous measurements of these processes are particularly complicated in the mesosphere at about 50 to 100 km height due to the remote location of this region. READ MORE
