1. Modelling Microwave Backscattering from Sea Ice for Synthetic-Aperture Radar Applications
Sammanfattning : 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. LÄS MER
2. SAR Remote Sensing of Forests, from Microwaves to VHF
Sammanfattning : 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. LÄS MER
3. Water Quality and Optical Properties of Swedish Lakes and Coastal Waters in Relation to Remote Sensing
Sammanfattning : 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. LÄS MER
4. Use of remote sensing and in situ observations of the atmosphere in chemical transport models
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. The layer that did not swim away : Broadband acoustic discrimination and characterization of ocean stratification
Sammanfattning : 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. LÄS MER
