Short summary
Ozone (O3) pollution harms rice production and threatens food security. To understand these impacts, we calibrated a crop model using unique data from experiments where rice was grown in open fields under controlled O3 exposure (free air). This is the first time such data have been used to improve a model's ability to predict how rice responds to O3 pollution. Our work provides a more accurate tool to study O3's effects and guide strategies to protect agriculture.
