Abstract

65–74% of light extinction is due to light scattering in Mexico City. Organic aerosols dominate both submicron mass loading and light scattering. Brown carbon and black carbon contribute 22% and 78% to the total light absorption, respectively. Road traffic and regional wildfires are the main contributors to light absorption. The aerosols' optical properties exhibit distinctive diurnal and seasonal patterns.
