Data for: Maize crops face high stomatal uptake during high exposure to ozone in an agroecosystem in the United States Corn Belt

Tropospheric ozone is a phytotoxic air pollutant. The stomatal uptake of ozone is a substantial sink of tropospheric ozone, but it can create oxidative stress within plants, reducing photosynthesis and crop yields. We measured the field-scale eddy covariance flux of ozone using a UV-absorption based instrument, the NASA Rapid Ozone Experiment (ROZE). This dataset presents ozone concentrations, ozone flux, and ozone deposition velocity at half-hourly time resolution. The ozone flux was measured using the eddy covariance technique at a maize (Zea mays) agriculutral field in central Illinois near Champaign, IL (40° 0' 22.2186", -88° 17' 25.5408") during July - Spetember 2023.
