21. Radar Measurements of Temporal Variation in a Boreal Forest
Sammanfattning : Synthetic aperture radar (SAR) on a satellite platform is a suitable technique for all-weather global monitoring of forest parameters such as biomass. This is important for increasing the accuracy of the global terrestrial carbon flux, the largest uncertainty in our current understanding of the Earth’s carbon cycle. LÄS MER
22. 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
23. Sea Ice and Ocean Environmental Applications of Spaceborn SAR
Sammanfattning : 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. LÄS MER
24. Radar Remote Sensing of Forests Using CARABAS and ERS
Sammanfattning : Forests cover more than 30% of the Earth's land surface, and represent an important resource. In order to manage this resource effectively, accurate and up-to-date information is required on the extent and state of the forests. Radar remote sensing offers the possibility of providing some of this information. LÄS MER
25. Estimation of change in forest variables using synthetic aperture radar
Sammanfattning : Large scale mapping of changes in forest variables is needed for both environmental monitoring, planning of climate actions and sustainable forest management. Remote sensing can be used in conjunction with field data to produce wall-to-wall estimates that are practically impossible to produce using traditional field surveys. LÄS MER
