OTERO, L. et al. Australian aerosol layers over argentine territory during november 2019. An. AFA [online]. 2020, vol.31, n.1, pp.01-06. ISSN 0327-358X.

On November 8, 2019 a dense feather of smoke was detached from the coasts of Australia due to the intense fires that affected the region. These layers of smoke were dragged by the winds to South America, arriving to the Argentine territory on November 14 and remaining in suspension for a day. In this work, the optical properties of suspended aerosols with satellite information and measurements from terrestrial are analyzed. The Angstrom coefficient is calculated and the type of aerosols present is classified. High values of aerosol optical thickness of 0,25 on average for 440 nm and Angstrom coefficients of 1,2 in the, evidence the presence of smoke in the local atmosphere.
