1. 16. 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.

3. 17. GIS and remote sensing based mapping of microtopography and vegetation composition in a boreal mire complex

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Nils Helge Havertz; [2023]
   Keywords : Microtopography modelling; Remote sensing; Boreal mixed mires; Object Based Image Analysis OBIA ; random forest RF ;

   Abstract : Small scale variations in mire surface elevation referred to as microtopography are fundamental characteristics of mire ecosystems especially in the boreal region. Microtopography commonly classified into hummocks and hollows play a major role in several ecological, hydrological and biogeochemical processes including vegetation composition and carbon and methane dynamics.

4. 18. Vulnerable Populations and Urban Heat Islands: A Spatial Analysis of Socio-Demographic Factors and Heat Exposure in Stockholm

   University essay from KTH/Geoinformatik

   Author : William Godée; Hugo Lemna; [2023]
   Keywords : UHI; Urban Heat Islands; Stockholm; Spatial Analysis; GIS; ArcGIS; Regression; Vulnerable Population; Urbana Värmeöar; Stockholm; Rumslig Analys; GIS; ArcGIS; Regression; Sårbar Population;

   Abstract : The important urban issue of urban heat islands in Stockholm is examined in this thesis. These places influence urban sustainability, liveability, and public health because of the much higher temperatures they experience relative to their surroundings. READ MORE

5. 19. FOREST LANDSCAPE STRUCTURE OF CAPERCAILLIE (TETRAO UROGALLUS) LEK SITES IN NORTHERN SWEDEN : Analysis of lek site characteristics

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Agnes Blomgren; [2023]
   Keywords : capercaillie Tetrao urogallus ; habitat selection; forest landscape structure; lek site;

   Abstract : The purpose of this study is to analyze which variables influence the capercaillie’s (Tetrao urogallus) selection of lek sites in northern Sweden by using remote sensing data. The lek site is a crucial area for the species’ reproductive success. READ MORE

6. 20. Remote Sensing of Cryospheric Surfaces : Small Scale Surface Roughness Signatures in Satellite Altimetry Data

   University essay from Umeå universitet/Institutionen för fysik

   Author : Petter Ideström; [2023]
   Keywords : Remote sensing; Altimetry; Arctic; Cryosphere; ICESat-2; Cryosat-2; Svalbard;

   Abstract : The Arctic cryosphere is experiencing a higher rate of warming compared to the rest of the world due to Arctic amplification. As glacier elevation change provide reliable evidence of climate change it is routinely measured by satellite altimeters. READ MORE
