Orchidee photosynthesis

WebAbstract. Aerosol- and cloud-induced changes in diffuse light have important impacts on the global land carbon cycle, as they alter light distribution and photosynthesis in vegetation canopies. However, this effect remains poorly represented or evaluated in current land surface models. Here, we add a light partitioning module and a new canopy light … WebWe used the process-based land surface model ORCHIDEE (ORganizing Carbon and Hydrology In Dynamic Ecosystems) that has been developed at the IPSL (Institut Pierre Simon Laplace, France).
