Dataset for Molecular-Level Insights into the Seasonal Formation of Organosulfates in a Mountain Atmosphere

Résumé fourni par la source

This dataset contains the supporting data for the seasonal characterization of organosulfates (OSs) in PM₂.₅ collected at Wuyi Mountain, southeastern China. It includes the elemental and molecular composition of CHOS and CHONS species detected during summer and winter, together with sample-resolved aerosol chemical composition and atmospheric parameters, including PM₂.₅, OM, OC, EC, temperature, relative humidity, aerosol pH, aerosol liquid water content, SO₂, Ox, nitrate, sulfate, ammonium, chloride, elemental components, sulfur and nitrogen oxidation ratios (SOR and NOR), and backward-trajectory cluster assignments. The dataset also includes the relative abundances of major molecular formula classes (CHO, CHON, CHN, CHS, CHOS, CHONS, and CHNS) and identified OS groups, including C2/C3 OSs, isoprene-derived OSs (OSi), monoterpene-derived OSs (OSm), monoterpene-derived nitrooxy-OSs (NOSm), and aliphatic-like OSs (OSali). These data support the analyses of seasonal molecular characteristics, atmospheric associations, and regional transport influences discussed in the manuscript.
