The ozone (O3) variations in southeast China are largely different between mountainous forest areas located inland, and lowland urban near the coast. Here, we selected these two kinds of to compare their similarities differences surface O3 variability from diurnal seasonal scales. Our results show that comparison with (coastal areas), (inland areas) characterized less human activates, lower precursor emissions, wetter colder meteorological conditions, denser vegetation covers. This can lead chemical production higher deposition rates inland areas. annual mean 8-h maximum concentrations (MDA8 O3) ~15 μg·m−3 (i.e. ~15%) than coastal day-to-day variation types is rather similar, a correlation coefficient 0.75 them, suggesting similar influences on large scales, such as weather patterns, regional transport, background O3. Over 2016–2020, all shows trend “rising then falling”, peak 2017 2018. Daily MDA8 correlates solar radiation most areas, while it correlated relative humidity most. Diurnally, during morning, increase faster seasons, mainly due temperature decrease humidity. While evening, mostly attributable titration effect Seasonally, both share double-peak concentrations, peaks spring autumn valleys summer winter. We found valley related Asian monsoon induces large-scale convections bringing local upward but blocking inflow downward, one winter low production. experienced more exceedance days (~30 per year) (~5-10 year), sources northeast. Overall, southeastern unique, reflecting collective impact geographic-related meteorology, concentrations.
