  1. 1. Changes in July albedo and its relationship with EVI over the last two decades in the Swedish alpine region

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Vera Grönvik Hende; [2023]
    Nyckelord :Shortwave albedo; Enhanced Vegetation Index EVI ; Alpine vegetation; Scandes; Surface albedo feedback; MODIS; Earth and Environmental Sciences;

    Sammanfattning : Vegetation in the subarctic is expected to respond to climate warming as its growth becomes less temperature limited. This has previously been recorded in the form of treeline advances and increasing shrub cover. Changes in vegetation cover may accelerate warming due to a decrease in summer albedo, in what is termed surface albedo feedback. LÄS MER

  3. 2. Intercomparison of a Dynamic Ocean for Earth-like Aqua-planets

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Fredrik Plane; [2022]
    Nyckelord :Astrobiology; Planets; Aqua-planets; Atmosphere and Ocean physics; Exoplanet; Habitability; General Circulation Model; GCM; Climate Modelling; Dynamic Ocean;

    Sammanfattning : I present herein an ensemble of ROCKE-3D aqua-planet simulations which I compare with the simulations presented in the work of Yang et al. (2019) and other similar works. The focus was on contrasting differences in the greenhouse effect between the models. LÄS MER

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

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Sammanfattning : 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

  5. 4. Meteorological Conditions on Nordenskiöldbreen Glacier, Svalbard (2009 – 2015)

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Niclas Bergman; [2017]
    Nyckelord :Svalbard; Nordenskiöldbreen; glacier; albedo; Svalbard; Nordenskiöldbreen; glaciär; albedo;

    Sammanfattning : Glacial environments in the Arctic are a much-studied topic as well as a field of research with strong influences regarding the current and future global climate of our planet. This report is focused on the meteorological conditions on Nordenskiöldbreen glacier from 2009-2015 and how they correlate with each other, the glacier surface and the surrounding terrain. LÄS MER

  7. 5. Modelling albedo in the ablation zone of the Greenland ice sheet

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Marie Rasmussen; [2014]
    Nyckelord :albedo; Greenland; Physics and Astronomy;

    Sammanfattning : Abstract An ice sheet always experience more or less melting during the summer. How much melting that occurs, is mostly determined by the albedo. Albedo is defined as the amount of the incoming shortwave radiation that gets reflected by a surface. When the sunlight starts melting the ice and snow in the summer, the albedo gets lower. LÄS MER
