This study highlights the different aerosol populations that are commonly observed in the central Amazon. Vertical gradients of aerosol optical and chemical properties were evaluated on different atmospheric conditions, and showed distinct characteristics of these particles. Intercontinental transport events bring to the region particles with a contrasting chemical composition, while vertical transport processes influence the aerosol properties by promoting the development of coating and aging.
