Short summary

We measured the net exchange (fluxes) of volatile organic compounds and ozone between a mixed temperate forest and the atmosphere over three years in Belgium. Many compounds were both emitted and deposited depending on the season and time of day. Emissions peaked in summer, while uptake was stronger in autumn. This unique long-term dataset improves our understanding of forest–atmosphere interactions and supports better air quality and climate models.
