SYMP 8-3 - From Remotely-Sensed SIF to Ecosystem Structure, Function, and Service: Harness Theory and Data

Tuesday, August 8, 2023
2:10 PM – 2:30 PM PDT
Location: C123
Solar-induced chlorophyll fluorescence (SIF) is a remotely sensed optical signal emitted during the light reactions of photosynthesis. The past two decades have witnessed an explosion in availability of SIF data at increasingly higher spatial and temporal resolutions, sparking applications in diverse research sectors (e.g., ecology, agriculture, hydrology, climate, and socioeconomics). These applications must deal with complexities caused by tremendous variations in scale and the impacts of interacting and superimposing plant physiology and three-dimensional vegetation structure on the emission and scattering of SIF. At present, these complexities have not been overcome. To advance future research, the two companion reviews aim to 1) develop an analytical framework for inferring terrestrial vegetation structures and function that are tied to SIF emission, 2) synthesize progress and identify challenges in SIF research via the lens of multi-sector applications, and 3) map out actionable solutions to tackle these challenges and offer our vision for research priorities over the next 5-10 years based on the proposed analytical framework.
