Daegu's air quality reflects South Korea's southeastern Geumho River basin's partial topographic enclosure between the Palgong and Biseul mountains, with vehicle traffic on surrounding expressways and the textiles, metal processing, and manufacturing corridor contributing local sources. Seasonal Chinese dust transport elevates PM10 during spring yellow dust episodes, while the basin's topographic enclosure creates concentration under calm inversions and the regional Northeast Asian industrial background maintains moderate to elevated South Korean inland metropolitan readings throughout the year.
