title: 2000–2020 Monthly Air Quality Index (AQI) Dataset of China at 1 km Spatial Resolution

description: This dataset provides monthly gridded Air Quality Index (AQI) data covering the entire territory of China from 2000 to 2020, with a spatial resolution of 1 km. The data were generated to support research on the associations between long-term/seasonal air pollution exposure and cardiovascular disease (CVD) risk in Chinese older adults (aged ≥65 years), as part of a study using the China Health and Retirement Longitudinal Study (CHARLS, 2011–2020) cohort. It captures fine-scale spatial and temporal variations in air quality across China, enabling precise linking of environmental exposure to individual health outcomes. China’s national standard (GB 3095–2018) as the maximum index among six criteria pollutants (PM₂.₅, PM₁₀, SO₂, CO, NO₂, O₃). Eighteen predictors were integrated to ensure accuracy, including meteorological variables (e.g., 2-m air temperature, 10-m wind speed from the China Meteorological Forcing Dataset), vegetation metrics (Normalized Difference Vegetation Index [NDVI], Net Primary Productivity [NPP]), anthropogenic factors (downscaled GDP, population density, Human Footprint Index), and soil properties (pH, soil organic carbon from China’s High-Resolution National Soil Information Grid). Four tree-based ensemble algorithms (Random Forest [RF], Gradient Boosting Machine [GBM], CatBoost, XGBoost) were compared, with the RF model selected as optimal (test set: R² = 0.83, Root Mean Square Error [RMSE] = 10.25, Mean Absolute Error [MAE] = 9.03) after validation via 10-fold geographic stratified cross-validation and 100 bootstrap iterations; Recursive Feature Elimination (RFE) further refined 14 core predictors to minimize overfitting. The dataset is provided as NCnet files (252 total, one per month) covering China (80°E–135°E, 15°N–53°N).

title: 2011–2020 China County-Level Excess Heat Factor (EHF) Related Metrics Data and Rcodes

description: The generated table "County-Level_EHF_Metrics_Final_Results_2011-2020.xlsx" contains county-level annual EHF (Excess Heat Factor) - related metrics in China from 2011 to 2020, with spatial units identified by `County_ID` (county code), `City_ID` (city code), `province`, and `city` (consistent with the county-level spatial unit definition in Section 2.2 of manuscript entitled "Heat-related frailty risks among middle-aged and older populations in China"). Key parameters are defined in line with the two manuscripts: `ehf_tday` represents the number of warm-season (June–September) days with valid EHF (&gt;0) calculated based on `Tavg` (daily average temperature, defined as (Tmax+Tmin)/2 per Maintext Eq.3); `ehf_avginten` is the average intensity of valid EHF (set to 0 if no EHF days, Section 2.2); `avg_temp` denotes the average `Tavg` during the exposure period (2/3/4 years before the target year, matching the exposure period mapping logic); `var` is the daily temperature variability, calculated as the mean of monthly standard deviations of `Tavg`. All metrics correspond to three temperature thresholds (p90/p925/p95, i.e., the 90th/92.5th/95th percentiles of county-level warm-season `Tavg` per Eq.4) and specific exposure periods (2-year exposure for p90/p925, 2/3/4-year exposure for p95, as required by the study design). Meanwhile, we have attached the R codes for the entire calculation process (including NC data preprocessing, EHF function calculation, and integration of county-level EHF metrics).
