- Abstract: Both human and natural processes influence air pollution in megacities. Analysis of sixteen years of pollutants from fourmonitoring sites (vehicular, commercial, residential and urban background (U-BG)) in the greater São Paulo Metropolitan Areafound significant differences in pollutant concentrations according to land use types in all temporal scales of analysis (from diurnalto monthly time series). In the diurnal/weekly cycles, concentrations of primary pollutants are two to three times higher in thevehicular and residential sites, compared to the U-BG site, where ozone (O3) is almost 50% higher. In the seasonal scale, carbonmonoxide (CO) concentrations increase 80% due to land use differences, and about 55% due to seasonaity. Seasonal variationsof nitrogen monoxide (NO) and O3 are of comparable magnitude to land use differences. For coarse particulate matter (PM10)and nitrogen dioxide (NO2),seasonal differences are greater than land use differences. In the longer time series, the U-BG siteshows stronger and statistically significant correlations between the monthly time series of outgoing longwave radiation (OLR)and O3 (0.48) and MP10 (0.37), compared to the vehicular site (0.33 and 0.22, respectively). ese resultsconfirms that urbanactivity and land useplay a significant role in pollutant concentrations for all scales of analysis, though its influence becomes lesspronounced with increasingly larger temporal scales, as air quality shis from a human-induced to a natural-induced system. esefindings may have implications for future decision-making and environmental, public health and transportation policies for similarmegacitiesinvolving land use change.
