1. 1. Exploring Urban Land Cover Changes and the Effect on Nocturnal Air Temperature Dynamics in Helsingborg - A temperature modeling made with TAPM

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Amanda Bäck; [2023-10-09]
   Nyckelord :Nocturnal Air Temperature; Intra-Urban Heat Island; Land Cover Classification; Deep learning; The Air Pollution Model TAPM ; Land Cover Change;

   Sammanfattning : In light of increasing global temperatures, urban areas face growing challenges related to heat stress. Alterations in land cover (LC) within cities contribute to changes in the intra-urban climate, predominantly driven by the replacement of vegetated surfaces with impermeable materials. LÄS MER

3. 2. Land Use and Land Cover Changes in Europe and the Impact on Near-Surface Wind Speed in Sweden

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Nils Philipp Stange; [2023-08-18]
   Nyckelord :;

   Sammanfattning : Investigations of Land use and land cover change (LULCC) have recently become of increasing interest. This trend occurs not only based of the importance of biogeochemical processes such as carbon sequestration, but also because of their climate impacts caused by changed biogeophysical properties.

4. 3. The Impact of Global Warming on Wind Power Potential in the Greater Horn of Africa

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Bromwel Apondi; [2023-08-17]
   Nyckelord :Near-surface wind speed; the Greater Horn of Africa; ERA5; Wind power density; CORDEX-Africa;

   Sammanfattning : The wind speed variability and wind power potential in the Greater Horn of Africa is analyzed in this study to fill a knowledge gap regarding if wind power can be used more as a source of energy for the region. This is investigated based on reanalysis data from ERA5, observed wind speeds, CORDEX-Africa regional climate models (RCMs) for future projections and a literature review. LÄS MER

5. 4. Monitoring deforestation in the Serranía de Chiribiquete in northern Colombian Amazon using time series analysis of satellite data

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

   Författare :Yuyang Qian; [2023]
   Nyckelord :Physical Geography and Ecosystem analysis; CCDC; Forest loss; Landsat; Sentinel-1; Change detection; NNP; FARC; Earth and Environmental Sciences;

   Sammanfattning : Deforestation monitoring is of significant importance for the ecosystem, climate change,and policy-making. The availability of optical and synthetic aperture radar (SAR) satellite remote sensing images, along with the development of time series change detection methods, has contributed to the increasing popularity of time series analysis in forest disturbance monitoring.

7. 5. Post-Fire Vegetation Recovery Monitoring using MODIS Time Series: A Case Study in California

   Kandidat-uppsats, KTH/Geoinformatik

   Författare :Julia Edje; [2023]
   Nyckelord :vegetation recovery; MODIS; HRT; EVI; fire; burn severity; land cover; climate zone; California;

   Sammanfattning : Human-caused forest fires have increased in magnitude and frequency, affecting global vegetation and requiring a re-evaluation of fire regimes. Changing fire regimes have led to reduced burned areas in fire- dependent ecosystems and increased areas in fire-independent ecosystems, resulting in changes in land cover and posing a threat to native plant communities.
