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

Tracking when trees leaf out or shed leaves reveals how forests respond to climate change, but collecting such data across large areas is costly. SwissPhenoCam repurposes cameras already installed across Switzerland for weather monitoring and tourism, turning existing infrastructure into an ecological observatory. The result is a freely available dataset covering over 5,800 tree-years across more than 20 tree species, documenting species-specific seasonal behaviours along elevation gradients.

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.
