ecosystems and is an important component of the terrestrial carbon cycle. Empirical light use
efficiency (LUE) models and process-based Farquhar, von Caemmerer, and Berry (FvCB)
photosynthetic models are widely used for GPP estimation. In this paper, the MODIS GPP
algorithm using the LUE approach and the Boreal Ecosystem Productivity Simulator (BEPS)
based on the FvCB model in which a sunlit and shaded leaf separation scheme is evaluated …
