  1. 1. Spatial downscaling of gridded soil moisture products using optical and thermal satellite data: the effects of using different vegetation indices

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tómas Halldórsson Alexander; [2023]
    Keywords : Physical Geography and Ecosystem Analysis; Remote Sensing; Soil moisture; Downscaling; Vegetation index; Earth and Environmental Sciences;

    Abstract : Soil moisture (SM) plays an important role in the exchange of heat and water between the surface and atmosphere, impacting water and energy cycles and the climate. Satellite remote sensing offers a global-scale estimation of SM; however, the coarse resolutions of satellite SM products, typically ranging from 25-50 km, are unsuitable for regional analysis.

  2. 2. Evaluation of Heat Mapping Techniques – the Case of Linköping

    University essay from Linköpings universitet/Institutionen för tema; Linköpings universitet/Filosofiska fakulteten

    Author : Pei Zhao; [2023]
    Keywords : correlation analysis; spatial analysis; land surface temperature LST ; mean radiant temperature MRT ; vulnerable population;

    Abstract : Land surface temperature (LST) and mean radiant temperature (MRT) are commonly used as proxies to evaluate urban heat environments. Many scholars use one of them to represent heat exposure when assessing the urban thermal environment. READ MORE

  3. 3. Determination of semi-aerobic landfill suitability in tropical developing countries using land surface temperature : A case study of an unmanaged open dump in transition in Yangon City region, Myanmar

    University essay from Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

    Author : Václav Pánek; [2022]
    Keywords : ;

    Abstract : Population growth rate increases rapidly, which reflects on Municipal Solid Waste(MSW) generation rates and the accumulation in unmanaged open dumps and landfills in developing countries. Consequences of improper MSW management and treatment are not only local or regional but global since Methane (CH4) emissions are responsible for a notable part of the total anthropogenic CH4 emissions.

  4. 4. Addressing the urban heat island effect in Stockholm : An analysis of its presence and relation to land cover and urban planning

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Fanny Igergård; [2021]
    Keywords : urban heat islands; land surface temperature; land cover; urban planning; GIS; urbana värmeöar; yttemperatur; marktäcke; stadsplanering; GIS;

    Abstract : As urbanization and global warming increase, an increasing importance is set on that urban planning processes take the possible effects of urban heat islands into account. In order to provide local city planners with site specific knowledge of the current situation in Stockholm, this study has explored the intra-urban heat island effect in Stockholm municipality by identifying major problem areas as well as addressing the statistical relationship between temperature and factors relating to land cover and urban planning strategies.

  5. 5. Exploring Spatiotemporal Relationships between InSAR-derived Land Subsidence and Satellite-based Hydrological Variables

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Yixin Zhang; [2021]
    Keywords : InSAR; Shabestar; subsidence; groundwater; hydrological variables; LSTM; Sentinel-1A; Geomatics; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : Shabestar basin in the East Azerbaijan province, Northwest Iran, where irrigation is the main groundwater consumer, has experienced large-scale subsidence and groundwater deletion, which poses a threat to the local agricultural activities, economic development, and food security. With the emergency of mitigating the risk, satisfying future demand for groundwater, and improving resilience considering climate change, this study proposes a satellite-based approach to explore the spatio-temporal relationships between measured subsidence and hydrological variables in the basin to assist groundwater management strategy.
