1. Sea Ice and Ocean Environmental Applications of Spaceborn SAR
Abstract : The worldwide focus on our changing environment has led to an increased need to observe and characterise a range of environmental phenomena. The Arctic Ocean is particularly sensitive to climate variations. READ MORE

2. Techniques for the validation of Odin and ENVISAT satellite data
Abstract : The depletion of ozone from the stratosphere and the impact of global warming have been identified as phenomena caused as a result of anthropogenic activity. Scientists are thus trying to find quicker and more reliable ways to analyse these environmental problems. READ MORE

3. Change Detection Using Multitemporal SAR Images
Abstract : Multitemporal SAR images have been used successfully for the detection of different types of environmental changes. The detection of urban change using SAR images is complicated due to the special characteristics of SAR images—for example, the existence of speckle and the complex mixture of the urban environment.

4. A Study of Polar Ozone Depletion in the Lower Stratosphere. -Dynamical assimilation of O3 and N2O data from Odin/SMR and ENVISAT/MIPAS
Abstract : For more than 20 years, a hole in the ozone layer has formed each spring over Antarctica when sunlight returns to the polar region. Similar albeit far less extensive ozone destruction has also been observed in the Arctic polar vortex after colder than average winters. READ MORE

5. Multitemporal Remote Sensing for Urban Mapping using KTH-SEG and KTH-Pavia Urban Extractor
Abstract : The objective of this licentiate thesis is to develop novel algorithms and improve existing methods for urban land cover mapping and urban extent extraction using multi-temporal remote sensing imagery. Past studies have demonstrated that synthetic aperture radar (SAR) have very good properties for the analysis of urban areas, the synergy of SAR and optical data is advantageous for various applications.
