FLuorescence EXplorer (FLEX): an optimised payload to map vegetation photosynthesis from space


Moreno, Jose F; Asner, Gregory P; Bach, Heike; Belenguer, Tomas; Kneubühler, Mathias; Schaepman, Michael E (2006). FLuorescence EXplorer (FLEX): an optimised payload to map vegetation photosynthesis from space. In: AIAA 57th International Astronautical Congress, Valencia (E), 2 October 2006 - 6 October 2006, 2065-2074.

Abstract

The FLuorescence EXplorer (FLEX) mission proposes to launch a satellite for the global monitoring of steady-state chlorophyll fluorescence in terrestrial vegetation. Fluorescence is a sensitive probe of photosynthetic function in both healthy and physiologically perturbed vegetation, and a powerful non-invasive tool to track the status, resilience, and recovery of photochemical processes and moreover provides important information on overall photosynthetic performance with implications for related carbon sequestration. The early responsiveness of fluorescence to atmospheric, soil and plant water balance, as well as to atmospheric chemistry and human intervention in land usage makes it an obvious biological indicator in improving our understanding of Earth system dynamics. The amenability of fluorescence to remote, even space-based observation qualifies it to join the emerging suite of space-based technologies for Earth observation. FLEX would encompass a three-instrument array for measurement of the interrelated features of fluorescence, hyperspectral reflectance, and canopy temperature. FLEX would involve a space and ground-truthing program of 3-years duration and would provide data formats for research and applied science.
