Remote sensing (RS) offers a unique possibility to investigate GPP. The overarching goal of this study is to enhance our knowledge on how environmentally induced changes of photosynthetic light-use efficiency (LUE) are linked with optical RS parameters. GPP was modeled using Monteith’s LUE-concept and optical-based GPP and LUE values were compared with synoptically acquired eddy covariance data. This research shows for the first time that including sun-induced fluorescence into modeling approaches improves their results in predicting diurnal courses of GPP. Our results support the hypothesis that air- or spaceborne quantification of sun-induced fluorescence yield may become a powerful tool to better understand spatio-temporal variations of photosynthetic efficiency and plant stress on a global scale.
