1. 16. Analysing seasonal snow cover trends and patterns on Svalbard

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Dhruv Maniktala; [2022]
   Keywords : snow cover; snow disappearance; snow onset; snow-free duration; CARRA; Svalbard;

   Abstract : Rapid warming in the Arctic is highly impacting the cryosphere in the region, causing melting of the sea ice, retreat of glaciers and reduction in the snow cover. If suffering further temperature increase, the albedo of the region would reduce due to higher absorption of the solar radiation in snow-free areas. READ MORE

3. 17. Evaluating forest wildfire effect on tree increment patterns for boreonemoral forests in Sweden: A pilot study using remote sensing

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Joanna Eaton; [2022]
   Keywords : Physical Geography and Ecosystem analysis; Remote sensing; Sentinel-2A; Forest wildfires; dNBR; NDVI; dNDVI; Dendrochronology; Atmospheric science and biogeochemical cycles; Earth and Environmental Sciences;

   Abstract : The release of anthropogenic greenhouse gases (GHGs) has substantially increased the global mean surface air temperature. Increases in global mean surface air temperature will lead to warmer and drier conditions, promoting more frequent, long-lasting, intense forest wildfires. READ MORE

4. 18. Agriculture monitoring using satellite data

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Graff Erik; [2021]
   Keywords : Sentinel; satellite; agriculture; monitoring; dynamic time warping; remote sensing;

   Abstract : As technology advances, the possibility of using satellite data and observations to aid inagricultural activities comes closer to reality. Swedish farmers can apply for subsidies for their land in which crop management and animal grazing occurs, and every year thousands of manual follow-up checks are conducted by Svenska Jordbruksverket (Swedish Board of Agriculture) to validate the farmers’ claims to financial aid.

5. 19. Using Sentinel-2 Satellite Images to Estimate Traits of Forage Grasslands

   University essay from SLU/Dept. of Agricultural Research for Northern Sweden

   Author : Niklas Zeiner; [2021]
   Keywords : Remote sensing; Forage grasslands; Sentinel-2; Dry matter yield; Canopy average height; Total leaf chlorophyll content; Partial least squares; Support vector machines;

   Abstract : In this project, regression models based on data from field measurements and spectral information extracted from satellite imagery were used to estimate traits of forage grasslands; dry matter yield, canopy average height and total leaf chlorophyll. Four fields at SLUs Röbäcksdalen field station were sampled on 22 occasions and a total of 198 samples, including measurement of the highest plant, canopy height, leaf chlorophyll content, canopy spectral reflectance and biomass were collected.

6. 20. Combination analysis of multispectral and radar satellite data

   University essay from Umeå universitet/Institutionen för fysik

   Author : Andreas Holmberg; [2021]
   Keywords : ;

   Abstract : Remote sensing technologies, such as satellite imagery, have proven to be a powerful tool for land cover classification when combined with machine learning algorithms. Depending on which type of sensor is used for the imagery, different properties of land cover classes may be distinguished. READ MORE
