Short summary

This study presents a comprehensive vertical gradient analysis of ozone (O₃) and its precursors in a remote mountainous background region of Southwest China from March to August 2024, we characterize the distribution of O₃ and key precursors, identify dominant controlling factors and quantify in situ O₃ production and loss pathways, highlighting a shift from NO_x-dominated O₃ control at lower elevations to increasing VOCs (Volatile Organic Compounds) sensitivity at higher altitudes.
