1. Evaporation and Heat-flux Aggregation in Heterogeneous Boreal Landscapes
Abstract : The boreal forests represent 8 % of all forested areas on the earth and have a significant role in the control of greenhouse gases and an impact on global climate change. The main objective of this thesis is to increase the understanding of how evaporation and heat-flux processes in the boreal forest zone are affecting the regional and global climate. READ MORE

2. Boundary-layer structure in flow over a heterogeneous surface
Abstract : Airborne measurements performed within the framework of NOPEX (Northern Hemisphere Land Surface Climate Processes Experiment) have been used to study processes related to fluxes of momentum, heat, and moisture in the boundary layer in the Swedish boreal region. The NOPEX area is characterized as heterogeneous with respect to vegetation. READ MORE

3. Land surface heat exchange over snow and frozen soil
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

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