1. Using forest reflectance modelling to estimate albedo for narrow-view satellites
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionenSammanfattning : Surface albedo estimations from remote sensing are invaluable for energy balance descrip- tions in climate research. The aim of this work is to evaluate the possibility of using Sentinel-2 satellite data to get the total albedo of a small, vegetated area. LÄS MER
2. Climatic effects of changes in radiative forcing due to clear-cutting in Sweden
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Land cover conversion affects climate by imposing changes in the surface properties and carbon dioxide fluxes. Forest management programs often disregard that modification in surface albedo influences the exchange of energy and climate sensitivity. LÄS MER
3. Arctic Loess as an Environmental Archive: Holocene Dust and Wildfire Record in West Greenland
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The largest wildfire ever observed in Greenland raged through its tundra during august 2017, and it is unknown if there have been similar wildfires in the area before satellite monitoring began in 1999. Arctic wildfires affect permafrost degradation, carbon storage of soils and the surface albedo of the Greenland Ice sheet – despite this, local fires have previously been ignored by researchers.

4. Evaluation of RCA & RCA GUESS and estimation of vegetation-climate feedbacks over India for present climate
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Popular summary Changes in climate modify the terrestrial vegetation distribution that in turn affects the climate system by altering the balance of radiation, water, momentum, CO2 and other important atmospheric gases. This entire process is termed as vegetation-climate feedbacks. These feedbacks are studied by regional earth system model. LÄS MER
5. Estimation of Evapotranspiration through remote sensing. Comparison between three different resolution sensors at Barrax field, Spain.
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : Nowadays importance of water balance regarding measurements and water cycle pathways are of prime interest in a new perspective. Global issues, like Earth warming, or regional planned uses of water, e.g. irrigation, demand an increase in accuracy and coverage of different components of the water balance. LÄS MER
