Code and processed results for PM2.5 health burden under alternative air quality standards in China, 2013–2024

This record contains calculation code and processed summary results supporting the analysis of PM2.5-attributable mortality and incidence under observed and counterfactual air quality standard scenarios in mainland China, 2013–2024. The package includes scripts for exposure-response function processing, attributable burden estimation, uncertainty analysis, PM2.5-attributable fraction and halving-target progress calculations, and GEMM sensitivity analysis. Third-party source datasets, including TAP PM2.5 grids, WorldPop population grids, IHME GBD 2023 estimates and exposure-response curves, are not redistributed and should be accessed from their original sources as documented in SOURCE_DATASETS.md.
