Abstract

En 中文

• A dynamic ozone stress module based on stomatal flux was integrated into BEPS. • Ozone effects were represented through both physiological and LAI structural pathways. • Parameter uncertainty was quantified using EFAST and constrained via GLUE. • The improved model enhanced GPP simulation consistency with flux observations. • Ozone sensitivity of GPP showed clear differences among vegetation types.
