Zaragoza's air quality benefits from the Ebro valley's channelling of powerful westerly winds from the Atlantic, with the Cierzo wind delivering clean air from the Navarra plains on prevailing wind days. Vehicle emissions from the ring road and surrounding motorways are the primary local source, while calm summer conditions allow ozone to accumulate from vehicle and agricultural emissions across the Ebro basin.
