      abstract     = {Terrestrial gross primary production (GPP) is an important
                      parameter to explore and quantify carbon fixation by plant
                      ecosystems at various scales. Remote sensing (RS) offers a
                      unique possibility to investigate GPP in a spatially
                      explicit fashion; however, budgeting of terrestrial carbon
                      cycles based on this approach still remains uncertain. To
                      improve calculations, spatio-temporal variability of GPP
                      must be investigated in more detail on local and regional
                      scales. 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. Diurnal courses of sun-induced
                      fluorescence yield (FSyield) and the photochemical
                      reflectance index of corn were derived from high-resolution
                      spectrometric measurements and their potential as proxies
                      for LUE was investigated. GPP was modeled using Monteith's
                      LUE-concept and optical-based GPP and LUE values were
                      compared with synoptically acquired eddy covariance data. It
                      is shown that the diurnal response of complex physiological
                      regulation of photosynthesis can be tracked reliably with
                      the sun-induced fluorescence. Considering structural and
                      physiological effects, 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 fluorescence yield,
                      photosynthetic efficiency and plant stress on a global
                      scale.},
