Replication package for: Calibrated Uncertainty for Air-Quality Forecasting: Conformal Prediction Intervals across an Eight-Station Pollution Gradient in Türkiye

This record contains the replication and audit materials supporting the manuscript “Calibrated Uncertainty for Air-Quality Forecasting: Conformal Prediction Intervals across an Eight-Station Pollution Gradient in Türkiye.” The study evaluates prediction-interval calibration for daily PM10 forecasting across eight Turkish air-quality monitoring stations, with PM2.5 analyses serving as secondary robustness checks. The computational replication workflow begins from the analysis-ready daily-data layer and covers modelling, conformal calibration, statistical comparisons, sensitivity analyses, and figure generation. The deposit includes the frozen computational replication package, checksums, model outputs, figures, documentation, clean-room reproducibility records, manuscript-to-output reconciliation records, method-to-code traceability records, independent recomputation results, negative and mechanism tests, and citation and bibliography audit records. Station-selection provenance for Table S5 is documented through the recovered and verified input–script–output chain and its associated audit package. The B5 primary inference and the V-a and V-b revision sensitivities are likewise supported by verified producer and audit records. Original analysis code is licensed under the MIT License.
