1. Leaf Area Index of Scandinavian Forests Methods Using in situ and Remotely Sensed Data
Sammanfattning : This thesis deals with methods of obtaining the leaf area index (LAI) from remotely sensed satellite data. Initially, in situ estimation methods were investigated, since the accuracy of the remotely sensed estimates is dependent on the quality of these estimates. LÄS MER
2. Remote sensing phenology at European northern latitudes - From ground spectral towers to satellites
Sammanfattning : Plant phenology exerts major influences on carbon, water, and energy exchanges between atmosphere and ecosystems, provides feedbacks to climate, and affects ecosystem functioning and services. Great efforts have been spent in studying plant phenology over the past decades, but there are still large uncertainties and disputations in phenology estimation, trends, and its climate sensitivities.

3. Modelling carbon uptake in Nordic forest landscapes using remote sensing
Sammanfattning : Boreal forests and peatlands store over 30% of the global terrestrial carbon in their vegetation and soil. but changing climate can compromise the current carbon stock. LÄS MER
