Chlorophyll fluorescence (ChlF) is the key to studying the physiological mechanisms of plant photosynthesis, quantifying the spatiotemporal pattern of vegetation photosynthesis, and accurately understanding the productivity of terrestrial ecosystems under the background of climate change. However, few studies have been conducted on combined observations of actively and passively induced ChlF. Here, we compared the advantages and disadvantages of active and passive observations of ChlF and showed the instrument composition of the combined observations of actively and passively induced ChlF at leaf and canopy scales. The application prospects of joint observations of actively and passively induced ChlF focus on exploring energy distribution among photosynthesis, fluorescence and heat dissipation at the chloroplast-leaf-canopy scale, clarifying the mechanism underlying the relationship between ChlF and gross primary productivity, verifying satellite-based sun-induced chlorophyll fluorescence and interpreting the shape of the ChlF spectrum. Our work suggests that the combined observation of actively and passively induced ChlF is essential to reveal the mechanisms underlying the relationships between fluorescence and photosynthesis at various scales and to improve vegetation productivity models at the global scale.
