B43L:
Sun-Induced Chlorophyll Fluorescence as a Proxy of Photosynthesis: Measurements, Modeling, and Applications from Field, Airborne, and Satellite Platforms I

Submit an Abstract to this Session



Session ID#: 31911

Session Description:
Chlorophyll fluorescence is intrinsically linked to photosynthetic machinery and is a novel indicator of photosynthetic activity. Advances have been made recently in the retrieval of sun-induced chlorophyll fluorescence (SIF) from ground-, air-, and space-based platforms. Higher spatial and temporal SIF products are foreseen from new satellite instruments (TROPOMI, TEMPO, Sentinel-4, and GEO-Carb) in the near future. SIF provides a unique way to measure photosynthesis and improve the quantification of carbon cycles at landscape, ecosystem, and global scales.

This session focuses on measurements, modeling, and applications of SIF in carbon cycle science at a range of temporal and spatial scales. We encourage contributions that discuss advances in observing and monitoring technologies of SIF from field, airborne, and satellite platforms, and welcome studies on the empirical and theoretical modeling of vegetation photosynthesis with SIF at multiple scales as well as studies that use SIF to understand the spatio-temporal variability of vegetation photosynthesis.
