11. GPS : superficial observations for deeper knowledge of the earth
Sammanfattning : .... LÄS MER
12. Methane dynamics in northern lakes : Insights from multi-scale observations
Sammanfattning : Methane (CH4) is a potent greenhouse gas which is emitted to the atmosphere from both natural and anthropogenic sources. Current evidence indicates that lakes account for a large part of the global emissions of CH4, but their contribution is difficult to quantify because of large temporal and spatial variability in processes leading to CH4 fluxes from lakes to the atmosphere.

13. Kilometer-scale climate modeling of precipitation in the Nordic region
Sammanfattning : Future changes in precipitation, in particular extremes, are among the most impact-relevant consequences of a warming climate driven by increases in atmospheric greenhouse gas concentrations. Still, climate model projections of future changes in regional and local precipitation remain uncertain. LÄS MER
14. Observing Sea Level Using Reflected Global Navigation Satellite System Signals
Sammanfattning : Sea-level rise due to global warming is predicted to have a large impact on human society, especially for populations living in coastal regions and on islands. It is therefore of great importance to monitor the sea level and to increase the understanding of the local hydrodynamic and meteorological responses to a global sea-level rise. LÄS MER
15. On Distribution Coefficients in Aquatic Systems
Sammanfattning : In this thesis, different types of chemical and physical distribution coefficients are identified, examined and used to describe the fate and transport pathways of substances in aquatic systems.Observations from field experiments in streams with non-reactive and reactive tracers constituted the basis for development of an advection-dispersion model.
