Variations of equivalent surface albedo and its influence on the photolysis rates of NO2 in a typical urbanized area of Shanghai

Key Points

• Photolysis rates of NO2 are significantly influenced by changes in surface albedo, showing a direct relationship.
• Increased surface albedo corresponds to a reduction in NO2 levels by approximately 15% in urban areas.
• Analysis of atmospheric data from Shanghai reveals the critical role of surface properties on pollutant dynamics.
• Findings highlight the need for considering surface albedo in urban air quality models.
