  1. 1. Experimental investigation of snow metamorphism at near-surface layers

    University dissertation from Luleå : Luleå University of Technology

    Author : Lavan Kumar Eppanapelli; Luleå tekniska universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Snow metamorphism; NIR reflectance; Snow and Ice; Radiative transfer equation; Paramterization; Snow properties; Tomography; Snow microstructure; Experimentell mekanik; Experimental Mechanics;

    Abstract : Snow metamorphism is a direct objective in many snow research areas, and its charac-terisation is a major challenge in areas including winter road maintenance, detection of icing on wind turbine blades, and snow quality mapping for skiing. A common effect of snow metamorphism is compaction, which can be investigated from the associated vari-ations in physical properties of snow. READ MORE

  2. 2. Snow particle size investigations using digital image analysis - implications for ground observations and remote sensing of snow

    University dissertation from Stockholm : Department of Physical Geography and Quaternary Geology (INK), Stockholm University

    Author : Susanne Ingvander; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; snow; remote sensing; particle size; Antarctica; in-situ sampling; seasonal snow; Physical Geography; naturgeografi;

    Abstract : During the past century climate warming has caused rapid changes in the Cryosphere. This has increased the need to accurately monitor rates of change in snow and ice in remote or sparsely populated areas where environmental observing capacity is limited. Monitoring snow cover requires understanding of the snow pack and the snow surface attributes. READ MORE

  3. 3. Boreal land surface water and heat balance Modelling soil-snow-vegetation-atmosphere behaviour

    University dissertation from Stockholm : KTH

    Author : David Gustafsson; KTH.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil; snow; land surface heat exchange; forest; arable land; eddy-correlation; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur;

    Abstract : The water and heat exchange in thesoil-snow-vegetation-atmosphere system was studied in order toimprove the quantitative knowledge of land surface processes.In this study, numerical simulation models and availabledatasets representing arable land, sub-alpine snowpack, andboreal forest were evaluated at both diurnal and seasonaltimescales.

  4. 4. Sustainable snow handling

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Karin Reinosdotter; Luleå tekniska universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Urban snow contains pollution that originates from sources such as atmospheric precipitation, traffic emission, and de-icing chemicals. These pollutants accumulate in the snow during the winter and are released when the snow starts to melt. READ MORE

  5. 5. Land surface heat exchange over snow and frozen soil

    University dissertation from Stockholm : KTH

    Author : David Gustafsson; KTH.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface energy balance; Snow; Boreal forest; SVAT models; Eddy-correlation Measurements; Latent heat flux; Sensible heat flux; Net radiation; Soil temperature; Aerodynamic roughness; Surface resistance; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur;

    Abstract : The energy exchange in the soil-snow-vegetation-atmospheresystem was studied to improve the quantitative knowledge of thegoverning processes. The lack of such knowledge contributes tothe uncertainty in the applicability of many existing modelsindependent of the temporal or spatial scale. READ MORE
