Impact of the vertical mixing induced by low-level jets on boundary layer ozone concentration

► The nocturnal O3 maxima occurred concurrently at multiple sites along the corridor. ► The residual layer (RL) is leaky in the presence of a strong low-level jet (LLJ). ► The role of LLJ-induced vertical mixing on boundary layer O3 is identified. ► Mixed-layer O3 concentration on the next day is reduced as a result of a leaky RL.
