  2. 6. Satellite Limb-Scatter Observations of Stratospheric NO2 and O3 -Retrievals, Validation and Applications

    Author : Samuel Brohede; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; satellite; NO2; Odin; limb-scatter; validation; OSIRIS; stratosphere; remote sensing; O3; retrieval;

    Abstract : Global observations of vertically resolved atmospheric constituents with high temporal and spatial sampling are crucial for various scientific assessments of ozone depletion and climate change. This thesis explains how such data can be retrieved from satellite limb-scatter observations. READ MORE

  4. 7. Mobile Satellite Broadcast and Multichannel Communications : analysis and design

    Author : Cristoff Martin; Björn Ottersten; Jack Winters; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; communications; satellite broadcast; mobile; MIMO; asymptotic analysis; spatial multiplexing; Signalbehandling; Signal processing; Signalbehandling;

    Abstract : In this thesis, analytical analysis and design techniques for wireless communications with diversity are studied. The impact of impairments such as correlated fading is analyzed using statistical models. Countermeasures designed to overcome, or even exploit, such effects are proposed and examined. 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
