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

This research paper details the development and evaluation of a soil moisture module for the DO3SE (Deposition of O3 for Stomatal Exchange) model to better estimate how soil water deficits influence stomatal conductance and ozone flux in European forest trees.

• The DO3SE model is used to estimate ozone deposition, stomatal flux, and vegetation impacts across Europe and is integrated into the EMEP (European Monitoring and Evaluation Programme) photochemical model to link ozone precursor emission scenarios to vegetation damage risk for policy purposes.
• Previous regional flux-based risk assessments were limited by the assumption that soil water deficits did not limit ozone flux, as there were no evaluated methods to model these deficits and their effect on stomatal conductance (gsto).
• The new soil moisture module for DO3SE employs the Penman-Monteith energy balance method for water cycling and uses empirical data on pre-dawn leaf water status to estimate transpiration control. The researchers tested four methods for estimating this control, ranging from simple relationships between soil water content/potential and gsto to complex methods involving plant capacitance and hydraulic resistance.
