No impact of tropospheric ozone on the gross primary productivity of a Belgian pine forest

Imbalance-P paper. Contact with Lore Verryckt: Lore.Verryckt@uantwerpen.be ; High stomatal ozone (O3) uptake has been shown to negatively affect crop yields and the growth of tree seedlings. However, little is known about the effect of O3 on the carbon uptake by mature forest trees. This study investigated the effect of high O3 events on gross primary productivity (GPP) for a Scots pine stand near Antwerp, Belgium over the period 1998-2013. Stomatal O3 fluxes were modelled using in situ O3 mixing ratio measurements and a multiplicative stomatal model, which was parameterised and validated for... Mehr ...
