Background/Question/Methods: We describe airborne measurements of solar-induced chlorophyll fluorescence (SIF) and field studies of plant physiology to quantify responses of tropical forests to environmental forcing agents. The study was conducted at the La Selva Biological Station in the Atlantic lowlands of Costa Rica.

Results/Conclusions: We demonstrate that high-frequency measurements from autonomous airborne imaging spectroscopy and LiDAR can be used to quantify diurnal changes in SIF and volumetric canopy water content.
