Deep convection over the Loess Plateau significantly enhances ozone pollution, with column ozone in the residual layer doubling during pollution episodes.
- Why it matters: Understanding ozone formation under intense solar radiation and deep convective boundary layers is crucial for effective regional air quality management, especially in industrial areas.
- What they did: A 15-day UAV-based observational campaign and box model analysis examined vertical ozone and precursor variations, revealing key drivers of pollution episodes and sensitivity profiles.
- The result: Findings show VOCs, especially aromatics and OVOCs, dominate ozone production, with deep convection facilitating vertical transport and chemical oxidation, informing targeted control strategies.
