Calibrating the Simple Biosphere Model for Amazonian tropical forest using field and remote sensing data. Part I: average calibration with field data

Abstract

In the course of this study, it was found that some of the existing literature on stomatal behavior for tropical species is inconsistent with the observed behavior of the complete canopy in Amazonia and that the rainfall interception store of the canopy is considerably smaller than originally specified in SiB. Also the turbulent transfer model used in SiB was modified to account for the effects of height-varying foliage density. Finally, it was demonstrated that there is a distinct annual cycle in the biophysical properties of the forest canopy which influences the partitioning of energy into sensible and latent heat fluxes. -from Authors
