Assessment of plant health and productivity is vital to ensure future food security of the global population under a changing climate. Chlorophyll fluorescence (CF), a signal emitted by green plants, can reveal this information. Although CF has revolutionised photosynthetic research, current measurements are limited to individual plants. Remote sensing of canopy CF is required for efficient management of agricultural crops, forests, and natural ecosystems and is crucial for accurate estimation of plant carbon assimilation and production. This project will deliver remote sensing technology to bridge the gap between leaf and canopy productivity and pave the way for understanding both artificial and solar induced canopy CF measured from space.

对植物健康和生产力的评估对于确保气候变化下全球人口未来的粮食安全至关重要。绿色植物发出的一种信号--叶绿素荧光(CF)可以揭示这一信息。尽管碳纤维使光合作用研究发生了革命性的变化，但目前的测量仅限于单个植物。冠层碳流量遥感是有效管理农作物、森林和自然生态系统所必需的，也是准确估计植物碳同化和生产的关键。该项目将提供遥感技术，以弥合树叶和树冠生产力之间的差距，并为理解从太空测量的人工和太阳诱导的树冠CF铺平道路。
