Reproducibility materials for Atmospheric Blocking Marks Elevated Compound Heat–PM2.5 Exposure across the Extratropics

Processed source-data tables, Supporting Information protocols, provenance records, and recovered manuscript-era pipeline and audit scripts supporting the manuscript “Atmospheric Blocking Marks Elevated Compound Heat–PM2.5 Exposure across the Extratropics”. The archive contains machine-readable source tables underlying the manuscript figures and key sensitivity analyses, provenance and quality-assurance records, and analysis/audit scripts recovered from the manuscript-era project workflow. Large third-party ERA5, CAMS EAC4, MERRA2_CNN_HAQAST_PM25, WorldPop, GHAP, and MODIS source products are not redistributed. These products remain available from their original providers and are identified in the manuscript and accompanying documentation. The archive supports reproducibility of the reported processed results but should not be interpreted as redistributing third-party raw datasets.
