Simulated soil CO$_2$ efflux and net ecosystem exchange in a 70-year-old Belgian Scots pine stand using the process model SECRETS

International audience ; Within the framework of the EU ECOCRAFT (European collaboration on CO$_2$ responses applied to forests and trees), we developed a stand scale process model to simulate short-term carbon (C) and water fluxes from a mixed coniferous/deciduous forest in Northern Belgium (51o31$'$ N, 4o22$'$ E). The model, termed SECRETS, is a sequential, multi-species and multiple layer simulator that uses process modules adapted from several sources. Namely, we adapted BIOMASS (maintenance respiration and water balance), and coded the sun/shade model (photosynthesis; modified for forest... Mehr ...
