Tropospheric ozone (O<sub>3</sub>) is a known greenhouse gas responsible for impacts on human and animal health and ecosystem functioning. In addition, O<sub>3</sub> plays an important role in tropospheric chemistry, together with nitrogen oxides. The determination of surface-atmosphere exchange fluxes of these trace gases is a prerequisite to establish their atmospheric budget and evaluate their impact onto the biosphere. In this study, O<sub>3</sub>, nitric oxide (NO) and nitrogen dioxide (NO<sub>2</sub>) fluxes were measured using the aerodynamic gradient method over a bare soil in an agricultural field. Ozone and NO fluxes were also measured using eddy-covariance and automatic chambers, respectively. The aerodynamic gradient measurement system, composed of fast response sensors, was capable to measure significant differences in NO and O<sub>3</sub> mixing ratios between heights. However, due to local advection, NO<sub>2</sub> mixing ratios were highly non-stationary and NO<sub>2</sub> fluxes were, therefore, not significantly different from zero. The chemical reactions between O<sub>3</sub>, NO and NO<sub>2</sub> led to little ozone flux divergence between the surface and the measurement height (less than 1% of the flux on average), whereas the NO flux divergence was about 10% on average. The use of fast response sensors allowed reducing the flux uncertainty. The aerodynamic gradient and the eddy-covariance methods gave comparable O<sub>3</sub> fluxes. The chamber NO fluxes were down to 70% lower than the aerodynamic gradient fluxes, probably because of either the spatial heterogeneity of the soil NO emissions or the perturbation due to the chamber itself.
