Short summary
In this paper, we provide the first comprehensive description of a dust episode occurred in South America in June 2015 through observations and numerical simulations. We have investigated the spatiotemporal distribution of aerosols and the emission process over complex terrain to gain insight into the key role played by the orography and the condition that triggered the long-range transport episode.
