Norway spruce (Picea abies) forests in the Czech Republic are seriously weakened due to prolonged and severe drought followed by increased attacks of bark beetle. Such trees are easily to be damaged by presence of tropospheric ozone (O3), the major secondary phytotoxic air pollutant.
In order to describe the effect of O3 during drought events, O3 deposition in a mountainous spruce forest (NE of the Czech Republic, Beskydy Mts., 908 m a.s.l.) was determined by micrometeorological techniques during the periods 2012-2016 and 2017-2019. An Inverse Lagrangian Transport Model (Raupach 1989) was used to calculate ecosystem-scale O3 flux from a within-canopy concentration gradient. In addition, an Evaporative/Resistance method (Turnipseed et al., 2009) was applied to quantify stomatal O3 flux from measured total flux.
