The process of photosynthesis feeds almost all living organisms on the planet, plays an important role in the global carbon cycle and directly impacts the climate on earth. Remote sensing of sun induced chlorophyll fluorescence (SIF) is applied for non-invasive monitoring of photosynthesis in terrestrial vegetation on various scales. However, the direct understanding of SIF as a proxy for photosynthesis is a field of ongoing research. Tower-based SIF retrieval by field spectrometers for autonomous long-term observation of vegetation aspires to gain further insight into ecosystem-specific seasonal dynamics of photosynthesis activity.
