Modelling of soil moisture to determine ozone flux to European forest trees

The paper details a new soil moisture module for the DO3SE model, designed to address a limitation in regional risk assessments where soil water deficits were previously assumed not to limit ozone flux. The module uses the Penman-Monteith energy balance method and empirical data on pre-dawn leaf water status to estimate the biological control of transpiration, testing four different methods ranging from simple soil water content relations to complex models incorporating hydraulic resistance and plant capacitance.

• The DO3SE (Deposition of O3 for Stomatal Exchange) model is used to estimate ozone deposition, stomatal flux, and vegetation impacts across Europe and is integrated into the EMEP photochemical model to link vegetation damage risk to O3 precursor emission scenarios for policy use.
• A significant gap in regional flux-based risk assessments has been the assumption that soil water deficits do not limit ozone flux, caused by a lack of evaluated methods for modelling these deficits and their effect on stomatal conductance (gsto).
• The developed soil moisture module employs the Penman-Monteith energy balance method for water cycling and tests four methods for estimating the biological control of transpiration, varying from simple soil water content relations to complex models involving plant capacitance and hydraulic resistance.
