GSR4B: Biomass Map Super-Resolution with Sentinel-1/2 Guidance

Plants affect the Amazon's water cycle through processes such as transpiration and evaporation. Characteristics related to leaf size and biomass have the most significant impact on atmospheric water content and land surface temperature, but they affect soil moisture content only minimally. These relationships also vary at extreme water cycle values and across Amazon subbasins. The study underscores the critical role of plants in maintaining the resilience of the Amazon’s hydrological processes.

For many safety-related applications such as road management, well-documented avalanches are important. To enlarge the information, webcams may be used. We propose supporting the mapping of avalanches from webcams with a machine learning model that interactively works together with the human. Relying on that model, there is a 90% saving of time compared to the "traditional" mapping. This gives a better base for safety-critical decisions and planning in avalanche-prone mountain regions.

Plants can impact the water cycle in the Amazon via transpiration and evaporation. Plants characteristics relating to leaf size and biomass have the strongest influence on atmospheric water content and land surface temperature, while having little effect on soil moisture content. The relationships also vary at extreme values of water process parameters and across Amazon subbasins. This study emphasizes the role of plants in maintaining the resilience of the Amazon's hydrological processes.

Soil organic carbon (SOC) is key player in the global carbon cycle. Afforestation on pastures potentially alters organic matter input and SOC sequestration. We investigated the effects of a Picea abies L. afforestation sequence (0 to 130 years) on a former subalpine pasture on SOC stocks and dynamics. We found no difference in the SOC stock after 130 years of afforestation and thus no additional SOC sequestration. SOC composition was altered due to a modified SOC input following afforestation.
