Abstract
Phenological modeling for tropical forests remains poorly developed and many global ecosystem models, like ORCHIDEE, assume that canopy dynamics of evergreen tropical forests show no seasonality. The current ORCHIDEE scheme fails to adequately model the seasonal variability of carbon fluxes observed in tropical evergreen forests. A better description of the underlying mechanisms that drive tropical forest canopy seasonal photosynthesis dynamics and phenology could possibly overcome this problem. To address this issue, seasonal variations in leaf phenology and photosynthesis dynamics for evergreen tropical forests were introduced and validated against in-situ carbon flux measurements. Both a seasonal photosynthetic capacity and a litterfall seasonality were introduced in ORCHIDEE and the resulting increased dry season photosynthesis and changed seasonal Net Ecosystem Exchange (NEE) patterns for flux tower sites in the Amazon were evaluated.
