The 4th June 2011 a volcano eruption at the Puyehue – Cordón Caulle chain in the south central region of Chile released an important amount of ash to the atmosphere. The cloud reached Argentina, Uruguay, Brazil, South Africa and Australia blocking the aerial transport. A coaxial multiwavelength backscatter Raman LIDAR, developed and operational in Buenos Aires, at the CEILAP – UNIDEF (MINDEF - CONICET), Lidar Division, (34.5° S, 58.5° W), collocated ground-based systems and overpassing satellite borne instruments observed this event. This lidar, is a tripled Nd:YAG laser, collecting also the nitrogen (from visible and ultraviolet) and water vapor Raman backscattered wavelengths. It also measures the water vapor mixing ratio profile at the corresponding Raman-shifted backscattered return. Additional information such as satellite imaging and AERONET aerosol optical depth were included on this study
