Quantifying the drivers of ozone formation using localized photochemical reactivity and double machine learning.

Surface ozone (O3) pollution remains severe in many Chinese cities despite declining precursor emissions, reflecting nonlinear interactions among emissions, meteorology, chemistry, and transport. Here, we integrated hourly observations from Yuncheng in the Fenwei Plain during 2020-2022 with a localized observation-cons...
