Industrial Sulfur Gas Concentration Dataset for SRU Forecasting

This dataset contains raw industrial H2S/SO2 concentration sequences and processed subsequences (via VMD-CEEMDAN) used in the study "Hybrid Multiscale Forecasting of SRU Sulfur Gas Concentrations Using Optimized PatchTST". It is provided to support the reproducibility of the forecasting results and performance metrics reported in the paper.
