The multi-scale insights into summer ozone sources and their impacts on maize yield over the North China Plain

Key Points

• Maize yield decreases when exposed to higher ozone concentrations, influencing agricultural productivity.
• A notable reduction of approximately 15% in maize yield correlates strongly with elevated summer ozone levels.
• Multi-scale analysis conducted across various regions of the North China Plain identifies key ozone sources impacting crops.
• Findings highlight the need for strategies to mitigate ozone pollution and protect agricultural yields.
