  4. 4. Model-Based Stem Volume Retrieval and Windthrow Detection using CARABAS and P-band SAR

    Detta är en avhandling från Umeå : Tillämpad fysik och elektronik

    Författare :Klas Folkesson; [2008]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CARABAS; remote sensing; forest monitoring; model-based stem volume retrieval; image segmentation; synthetic aperture radar SAR ; P-band; windthrow detection;

    Sammanfattning : Radar remote sensing is an efficient method for monitoring forests over large areas. Radar waves transmitted from a system carried by a satellite or an aircraft interact with trees on the ground, and the reflected waves are used to form images which are independent of weather and light conditions.

  5. 5. Satellite measurements and climate modelling of water in the tropical upper troposphere

    Detta är en avhandling från Umeå : Tillämpad fysik och elektronik

    Författare :Marston Sheldon Johnston; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Model; Satellite; Climate; Humidity; Radiation; Tropics;

    Sammanfattning : The International Panel on Climate Change (2007) has identified key areas of uncertainty with regards to future climate change, e.g., the upper troposphere. A portion of the uncertain- ties come from climate models and this makes model accuracy very important. LÄS MER
