Short summary
The environment inside a forest canopy is often not represented in large atmospheric models. This study uses a detailed canopy model to understand trace gas emissions and chemistry within the Amazon rainforest. We show escape of trace gases from the canopy to the atmosphere can depend on turbulence and vary over the day, which is currently not included in atmospheric models. We show that the atmospheric composition above the Amazon and within the canopy is strongly affected by forest fires.
