In our recent study in Global Change Biology (Li et al., ), we examined the relationship between solar-induced chlorophyll fluorescence (SIF) measured from the Orbiting Carbon Observatory-2 (OCO-2) and gross primary productivity (GPP) derived from eddy covariance flux towers across the globe, and we discovered that there is a nearly universal relationship between SIF and GPP across a wide variety of biomes. This finding reveals the tremendous potential of SIF for accurately mapping terrestrial photosynthesis globally.
在我们最近发表于《全球变化生物学》（Li等人）的研究中，我们研究了从轨道碳观测站-2（OCO-2）测量的太阳诱导叶绿素荧光（SIF）与全球涡度协方差通量塔得出的总初级生产力（GPP）之间的关系，并且我们发现，在各种各样的生物群落中，SIF和GPP之间存在近乎普遍的关系。这一发现揭示了SIF在全球准确绘制陆地光合作用方面的巨大潜力。
