Final Report Abstract

The objective of the GlobFluo project was to implement a junior research group focused on the space-based monitoring of the sun-induced fluorescence (SIF) signal emitted by vegetation for a global-scale assessment of photosynthetic processes. GlobFluo activities dealt with both the measurement of SIF from spaceborne spectroscopic measurements and the interpretation and exploitation of such measurements for an improved understanding of vegetation functioning at the ecosystem scale. This research led to several key studies in the field, especially regarding the retrieval of SIF from space-based measurements through data-driven approaches, the interpretation of the data with attention to canopy structure effects and the utilisation of the data to represent photosynthetic processes in crops, tropical rainforests and boreal evergreen forests. The optimal timing of GlobFluo made it possible that several of the papers produced by the group have become important references in the literature, and are now listed as Highly Cited Papers by Web of Science.
