The study investigates the impact of temperature-dependent evaporative anthropogenic volatile organic compound (AVOC) emissions on surface ozone pollution in the Beijing–Tianjin–Hebei (BTH) region of China during summer 2017. The authors parameterized the temperature dependence of evaporative AVOC fluxes in a regional air quality model and evaluated its effects on ozone concentrations. The results show that the temperature dependency of AVOC emissions increased the simulated ozone-temperature sensitivity by 1.0 to 1.8 μg m⁻³ K⁻¹, comparable to the sensitivity driven by biogenic VOC emissions (1.7 to 2.4 μg m⁻³ K⁻¹). The enhanced ozone concentrations due to temperature-induced AVOC increases were localized and more significant in urban areas. The inclusion of temperature-dependent AVOC emissions improved the model's performance on ozone exceedance days. The study highlights the importance of temperature-dependent AVOC emissions in regional air quality and meteorology interactions, providing insights for better air quality management and emission reduction strategies.The study investigates the impact of temperature-dependent evaporative anthropogenic volatile organic compound (AVOC) emissions on surface ozone pollution in the Beijing–Tianjin–Hebei (BTH) region of China during summer 2017.
