   Sammanfattning : Recent trends of permafrost thawing in the subarctic are expected to cause increased release of dissolved organic carbon (DOC) to inland waters, which might have cascading effects on downstream aquatic ecosystems and release of CO2 to the atmosphere. This study therefore aimed at evaluating the applicability of an empirical band ratio algorithm for estimating chromophoric dissolved organic matter (CDOM; a proxy for DOC) from the easily accessible satellite images Landsat TM-5, to counter the inaccessibility of the region in general.

3. 2. Forest damage assessment in the Black Triangle area using landsat TM, MSS and forest inventory data

   Magister-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Sören Mathias Hese; [1995]
   Nyckelord :Landsat TM; Black Triangle area; forest damage assessments; geography; physical geography; Landsat MSS; forest inventory data; Earth and Environmental Sciences;

   Sammanfattning : The main objective of this work was the evaluation of TM (Thematic Mapper) and MSS (Multi Spectral Scanner) data of Landsat 1 and 5 for a large scale forest damage assessment in the black triangle region. The area covers the Krusne Hory and neighboring mountain areas (border area of Germany, Poland and the Czech Republic. LÄS MER
