Short summary
This study examines how dust transport modulates oxalic acid formation pathways in aerosols across different elevations of Mount Hua. During dust events, oxalic acid and precursors shift from fine to coarse particles, with concurrent heterogeneous reactions on coarse particle surfaces. The characteristic isotopic fractionation signatures accompanying these transformations yield novel theoretical frameworks for elucidating aerosol aging mechanisms in mountainous environments.
