Short summary
This study analyzes nitrogen dioxide available data in Catalonia, a region with diverse geography and climate, by comparing satellite- and ground-based data from 2022–2023. Analyses at various scales showed a moderate overall correlation – stronger in suburban areas and weaker in urban zones. Correlations peaked in winter and autumn, likely due to stable weather. The findings suggest that satellite data can complement ground monitoring but require adjustments for regional and climatic variations.
