Abstract (English):
Solar-induced fluorescence is a promising indicator of plant photosynthetic activity for monitoring ecosystem productivity on a global scale. In this work, photosynthetic activity of different ecosystem types in the south of Western Siberia was assessed using TROPOMI data for the period 2018–2024. The relationships between solar-induced fluorescence and key temperature and humidity parameters of the environment, as well as vegetation indices, were investigated. Additionally, relationships among these parameters themselves were analyzed. The analysis was performed both for the whole target region and for individual administrative units.
