1. Snow particle size investigations using digital image analysis - implications for ground observations and remote sensing of snow
Sammanfattning : 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. LÄS MER
2. Hydrological Seasonal Forecasting
Sammanfattning : In Sweden, almost half of the electricity produced comes from hydropower. However, the amount of water in the reservoir catchments is not evenly distributed throughout the year. During the colder months, precipitation usually falls as snow and accumulates into a snowpack. LÄS MER
3. Boreal land surface water and heat balance : Modelling soil-snow-vegetation-atmosphere behaviour
Sammanfattning : 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. Seasonal snow storage for cooling applications
Sammanfattning : Seasonal snow storage for cooling applications is an ancient technique now being revived in different parts of the world. From June 2000 the first Swedish large-scale snow cooling plant provides for comfort cooling at the hospital in Sundsvall. The snow is thermally insulated by a 0. LÄS MER
5. Land surface heat exchange over snow and frozen soil
Sammanfattning : 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. LÄS MER
