Solar Induced Chlorophyll Fluorescence

Solar-induced chlorophyll fluorescence (SIF) measurements from spaceborne and ground-based platforms provide a powerful tool for studying agricultural and forest ecosystems by offering direct insights into plant photosynthetic activity. Spaceborne SIF observations enable large-scale monitoring of vegetation health, stress responses, and carbon uptake dynamics across diverse ecosystems, facilitating global assessments of productivity and drought impacts. Ground-based SIF measurements, with higher temporal and spatial resolution, allow for detailed process-level investigations, validation of satellite observations, and refinement of radiative transfer models. The integration of spaceborne and ground-based SIF data enhances our ability to track ecosystem responses to environmental changes, optimize crop management strategies, and improve models of carbon and water cycling in terrestrial ecosystems.
