Short summary
Dense canopy weakens turbulent mixing, leading to significant CO2 storage (Fs), a key part of net ecosystem exchange (NEE) measured using eddy covariance. Gust-biased Fs measurements complicate NEE estimation in forests with complex terrain. We analyzed gust-induced CO2 fluctuations and their impact on Fs. Fs and its contribution to NEE can be explained by terrain complexity and turbulent mixing. This work highlights how gusts over complex terrain affect the Fs and NEE measurements.
