Key Points

This research aims to integrate satellite-derived nitrogen dioxide data with ground-level measurements for improved spatial distribution modeling in temperate climates.
Developed a geographical predictive model utilizing Random Forest Regressor.
Combined ground-truth data from OpenAQ with Sentinel-5P TROPOMI satellite observations.
Model assessed from January 2023 to January 2025 with a coefficient of determination (R²) of 0.4337.
Model achieved a mean absolute error (MAE) of 8.25 µg/m³ in estimating ground-level NO₂ concentrations.
Demonstrated strong ability to resolve spatial variability in NO₂ using satellite inputs.
Validated the effectiveness of machine learning for localized air quality monitoring in regions lacking dense sensor networks.
