  1. 1. Using forest reflectance modelling to estimate albedo for narrow-view satellites

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionen

    Author : Nick Bergmans; [2023]
    Keywords : satellite; remote sensing; albedo; surface reflectance; vegetation; forest; machine learning; albedo estimation; Earth and Environmental Sciences;

    Abstract : 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. READ MORE

  2. 2. Climatic effects of changes in radiative forcing due to clear-cutting in Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Iris Muzic; [2019]
    Keywords : Physical Geography and Ecosystem Science; land-cover change; ICOS; albedo; carbon dioxide; radiative forcing; clear-cutting; Earth and Environmental Sciences;

    Abstract : 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. READ MORE

  3. 3. Arctic Loess as an Environmental Archive: Holocene Dust and Wildfire Record in West Greenland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Lars Petter Hällberg; [2018]
    Keywords : aeolian dust; IRSL; luminescence dating; charcoal analysis; magnetic susceptibility; wildfire;

    Abstract : 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. 4. Evaluation of RCA & RCA GUESS and estimation of vegetation-climate feedbacks over India for present climate

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nitin Chaudhary; [2011]
    Keywords : India; vegetation feedbacks; geography; climate change; GCMs; Validation; physical geography; RCMs; Earth and Environmental Sciences;

    Abstract : 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. READ MORE

  5. 5. Estimation of Evapotranspiration through remote sensing. Comparison between three different resolution sensors at Barrax field, Spain.

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : John Diego Sierra Torres; [2008]
    Keywords : geomorphology; Physical geography; Evapotranspiration and semote sensing; S-SEBI Model; Water balance; Environmental Satellite images applications; Environmental studies; Miljöstudier; Natural science; climatology; cartography; Naturvetenskap; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geografi; teknisk geologi; pedology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Abstract : 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. READ MORE
