Quantification of global land photosynthesis at high resolution and in real-time is ‘holy grail’ for ecologic research and agricultural applications. The emergence of new remote sensing data on solar-induced chlorophyll fluorescence (SIF), an optical signal emitted when light is absorbed by leaves, opens new opportunities to quantifying photosynthesis over the land-surface at global scale.
Yu et al.  use innovative computational techniques and intelligent stratification of earth’s biomes to produce a data set that takes us one step closer to making real-time global assessments feasible. The high resolution, consistent, and spatially contiguous data product developed in this study will greatly aid in a variety of applications aiming to understand the ecophysiological function of vegetation, such as drought monitoring and mitigation, agricultural planning and yield estimation, and remote sensing data benchmarking.
