Correction to “Quantifying Multi-pollutant Co-exposure via Deep Learning-Based Simultaneous Prediction Using Geostationary Satellite Data”

The legend colors for NO₂ and O₃ were interchanged in Figure . This has been corrected in the revised figure. The legends in the related time series plots have also been corrected in Figures S16 and S17 in the Supporting Information, and the Supporting Information has been updated accordingly. The hourly O₃ time-series and corresponding statistics in Figure (BTH) and Supporting Information Figures S16 (YRD) and S17 (SMA) have been corrected. The underlying model predictions remain unchanged. Accordingly, the related sentence in the manuscript was corrected as follows: In BTH, the hourly R² and nRMSE for O₃ were updated from 0.88 to 0.92 and from 0.30 to 0.18, respectively. The sentence describing YRD and SMA performance was corrected from “Performance in YRD and SMA was similarly strong (overall nRMSE < 0.21 and 0.25, respectively)” to “Performance in YRD and SMA was similarly strong (overall nRMSE < 0.21 and 0.32, respectively)” (Figures S16 and S17).

Daily and hourly time series of multiple air pollutants in BTH (unseen stations). Time-series validation results at unseen stations are shown on a daily scale in 2021 and on an hourly scale from March to April 2021 for the key hotspot region, BTH. To represent overall trends, hourly concentrations from seven unseen stations within the BTH region were averaged. Statistic metrics (R ², RMSE, and nRMSE) are displayed in the upper-left corner of each panel.
