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

   University essay from KTH/Geoinformatik

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

   Abstract : 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.

3. 2. Changes in July albedo and its relationship with EVI over the last two decades in the Swedish alpine region

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Vera Grönvik Hende; [2023]
   Keywords : Shortwave albedo; Enhanced Vegetation Index EVI ; Alpine vegetation; Scandes; Surface albedo feedback; MODIS; Earth and Environmental Sciences;

   Abstract : Vegetation in the subarctic is expected to respond to climate warming as its growth becomes less temperature limited. This has previously been recorded in the form of treeline advances and increasing shrub cover. Changes in vegetation cover may accelerate warming due to a decrease in summer albedo, in what is termed surface albedo feedback. READ MORE

4. 3. 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.

5. 4. Impact of Sea Surface Temperature and Salinity on Phytoplankton blooms phenology in the North Sea

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Krystyna Muszel; [2023]
   Keywords : Geography; GIS; North Sea; phytoplankton; bloom; phenology; remote sensing; TIMESAT software; Earth and Environmental Sciences;

   Abstract : Various environmental forcings can affect phytoplankton blooms, resulting in changes in bloom timing and abundance, which can have many far-reaching consequences. Understanding bloom phenology is crucial to predict and counter any potential harmful changes. READ MORE

6. 5. Evaluation of the effect of conflict on fire and GPP in Ukraine

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Lilith Kastens; [2023]
   Keywords : Climate Change; Armed Conflict; Fire; GPP; Remote Sensing; Russia-Ukraine War; Earth and Environmental Sciences;

   Abstract : The war in Ukraine in 2022 has caused environmental damages on different scales which come with their own challenges. One of the factors that can cause environmental damage is vegetation fire. READ MORE
