| contents | <p class="isSelectedEnd">This record contains machine-readable Supplementary Datasets S1–S4 associated with the manuscript “WSOC-Based SOC Estimates and FT-ICR MS Fingerprints Differentiate Regional Wintertime SOA Regimes in PM2.5 across Five Northeast Asian Cities.”</p> <p class="isSelectedEnd">The datasets support analyses of wintertime PM2.5, water-soluble organic carbon (WSOC), secondary organic carbon (SOC), source-diagnostic correlations, FT-ICR MS molecular-formula annotations, and putative molecular-transformation patterns across five Northeast Asian sampling sites: Ulaanbaatar (UB), Beijing (BJ), Seosan (SS), Seoul (SE), and Noto (NT). The coordinated winter campaign was conducted from 15 December 2020 to 14 January 2021.</p> <p class="isSelectedEnd">The deposited files include:</p> <p class="isSelectedEnd">Supplementary Dataset S1: Daily aerosol composition, harmonized levoglucosan concentrations, WSOC-based biomass-burning correction, WSOCBB, SOC, and POC estimates.</p> <p class="isSelectedEnd">Supplementary Dataset S2: Source-diagnostic paired data used for K⁺–OC and Ca²⁺–OC/PM2.5 correlation analyses.</p> <p class="isSelectedEnd">Supplementary Dataset S3: Full FT-ICR MS molecular-formula annotation dataset, including sample-level and site/type-level summaries.</p> <p class="isSelectedEnd">Supplementary Dataset S4: Molecular-transformation rule datasets, including the full 30-rule mass-shift database and the curated 20-rule set used in the manuscript analyses.</p> <p class="isSelectedEnd">For SOC estimation, a uniform (WSOC/OC)BB value of 0.70 was applied across all sites. The site-specific effective OCBB/levoglucosan conversion factors used for biomass-burning correction were 7.76, 4.41, 4.35, 4.25, and 4.28 for UB, BJ, SS, SE, and NT, respectively. Levoglucosan concentrations were harmonized to µg m⁻³, and the SE levoglucosan values were corrected for a 1000-fold scale difference before SOC calculation.</p> <p>The formatted Supporting Information file, including supplementary tables, figures, and methodological details, is submitted separately through the journal submission system.
