However, interpreting top-of-canopy (TOC) SIF in relation to photosynthesis remains challenging due to canopy structure and Non-photochemical quenching. Therefore, ground-based, high-spatial-resolution data sets are needed to characterize the described effects and to be able to downscale TOC SIF to the leafs where the photosynthetic processes are taking place.</abstract><sumDscr/><notes>Peng, H., Cendrero-Mateo, M.
