1. 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

2. 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.

3. Surface energy exchange and land-atmosphere interactions of Arctic and subarctic tundra ecosystems under climate change
Abstract : The surface energy balance determines the functioning of any ecosystem on the Earth but is still poorly understood in Arctic and subarctic biomes. In a dynamic system, such as the Earth’s climate, any change in its characteristics modifies the exchange of energy, water, and greenhouse gases between the surface and the atmosphere. READ MORE

4. Air-Sea Exchange of Momentum and Sensible Heat Over the Baltic Sea
Abstract : Long term measurements are used to explore the wave impact on the momentum and sensible heat transfer in the marine atmospheric surface layer. This is important in determining the boundary conditions of atmosphere-ocean coupled models of many scales. READ MORE

5. The interplay between atmosphere, hydrology and land use by environmental modelling
Abstract : Interactions between land surface and atmosphere induced by human activities and natural environmental dynamics act on a time scale that varies from seconds to millions of years. It is by exchanging heat, water, energy and carbon that land surface and atmospheric processes are closely interrelated and influence each other in reciprocal ways. READ MORE
