  2. 1. Modelling Microwave Backscattering from Sea Ice for Synthetic-Aperture Radar Applications

    Author : Anders Carlström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synthetic-aperture radar; microwave; surface roughness; sea ice; backscattering models;

    Abstract : The spaceborne synthetic-aperture radar (SAR) is considered one of the key instruments for monitoring the ice cover in polar oceans and regional seas. This thesis is concerned with applications of electromagnetic scattering theory and SAR system theory for modelling the response of different types of sea ice in SAR imagery. READ MORE

  4. 2. SAR Remote Sensing of Forests, from Microwaves to VHF

    Author : Hans Israelsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave; backscattering models; SAR; VHF; vegetation;

    Abstract : The number of SAR systems available for civilian remote sensing purposes has grown in the nineties. A Synthetic Aperture Radar produces high resolution images of the earth independent on daylight and atmospheric conditions. This thesis mainly examines the applications of SAR remote sensing to monitoring forested areas. READ MORE

  5. 3. Water Quality and Optical Properties of Swedish Lakes and Coastal Waters in Relation to Remote Sensing

    Author : Niklas Strömbeck; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; water quality; inherent optical properties; remote sensing; bio-optical models; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; limnologi; Limnology;

    Abstract : Semi-analytical models for remote sensing of water quality parameters need to be parameterized with specific inherent optical properties. In this thesis, data on specific inherent optical properties of Swedish lakes and coastal waters is presented. Also, the problems of measuring in situ spectral backscattering are addressed.

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

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

    Abstract : 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. READ MORE

  7. 5. The layer that did not swim away : Broadband acoustic discrimination and characterization of ocean stratification

    Author : Elizabeth Reed-Weidner; Martin Jakobsson; Richard Hobbs; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acoustical Oceanography; acoustics; oceanography; stratification; remote sensing; maringeologi; Marine Geology;

    Abstract : Ocean stratification plays a critical role in many oceanographic processes. The magnitude of mixing between stable water masses is regulated, in part, by the intensity of stratification. READ MORE
