  1. 11. Change of heating fuel consumption patterns produced by the economic crisis in Greece

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

    Författare :Panagiotis Patrinos; [2021]
    Nyckelord :geography; GIS; atmospheric pollution; Greece; household heating systems; heating fuel; economic Crisis; air Quality; satellite data; virtual stations; regression analysis; air pollutants mapping; anthropogenic factors; Earth and Environmental Sciences;

    Sammanfattning : The economic crisis in Greece resulted in a change in residential heating fuels utilized, which in turn resulted in a change of air quality over Greater Athens Area. The aim of this study was to investigate the effects of economic crisis in air quality over Attica by examining the change in air pollutants’ concentrations before, during, and after the onset of the economic crisis in Greece and to associate this change with the change in fuels used for residential heating.

  2. 12. A remote-sensing approach to studying drought resistance in Swedish old-growth and production forests

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

    Författare :Julika Wolf; [2020]
    Nyckelord :Physical Geography and Ecosystem Analysis; drought impacts; old-growth forests; forest management; remote sensing; Earth and Environmental Sciences;

    Sammanfattning : Boreal forest ecosystems are predicted to experience hotter and drier summers due to climate change, leading to more frequently reduced soil water availability and an increased risk of droughts, as was already the case in Northern Europe during the severe summer drought of 2018. Prolonged water stress in forest ecosystems can lead to impacts ranging from reduced photosynthesis to forest dieback. LÄS MER

  3. 13. Detection of slush on the Greenland Ice Sheet using Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery

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

    Författare :Viktor Wu; [2020]
    Nyckelord :slush; Greenland Ice Sheet GrIS ; surface mass balance SMB ; sea level rise SLR ; satellite imagery; Earth and Environmental Sciences;

    Sammanfattning : Sea Level Rise (SLR) is a growing global concern that is heavily influenced by a warming climate. Because of a potentially large added mass to the ocean through ice melt, the Greenland Ice Sheet (GrIS) plays an important role in the contribution to SLR. LÄS MER

  4. 14. Wildfire Hazard Mapping using GIS-MCDA and Frequency Ratio Models : A Case Study in Eight Counties of Norway

    Master-uppsats, Högskolan i Gävle/Avdelningen för datavetenskap och samhällsbyggnad

    Författare :Walelegn Mengist Zeleke; [2019]
    Nyckelord :Wildfire; GIS; MCDA; Frequency Ratio; Hazard Map; Constraint Criteria; Factor Criteria; AUC;

    Sammanfattning : Abstract A wildfire is an uncontrollable fire in an area of combustible fuel that occurs in the wild or countryside area. Wildfires are becoming a deadly and frequent event in Europe due to extreme weather conditions. In 2018, wildfires profoundly affected Sweden, Finland, and Norway, which were not big news before.

  5. 15. Vegetation phenology derived using the plant phenology index and the normalized difference vegetation index for the Balkan peninsula, south-eastern Europe

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

    Författare :Aleksandra Ivanova; [2019]
    Nyckelord :physical geography; ecosystem analysis; phenology; vegetation; climate change; remote sensing; plant phenology index; PPI; timesat; Balkan peninsula; Earth and Environmental Sciences;

    Sammanfattning : This study analyses the performance of the satellite derived Plant Phenology Index (PPI) against the Normalized Difference Vegetation Index (NDVI) for estimating start of season (SOS) and end of season (EOS) of vegetation growth in part of the Balkan Peninsula, Southeastern Europe (2000 – 2016). Results revealed that PPI and NDVI differ considerably; SOS and EOS may diverge by more than one month between the two indices. LÄS MER
