Characterization and evolution of tropospheric plumes from Lascar and Villarrica volcanoes, Chile

Abstract:

Direct sampling (filter pack and impactor) and remote sensing (ultraviolet spectroscopy and Sun photometry) of the plumes of Lascar and Villarrica volcanoes, Chile, reveal that both are significant and sustained emitters of SO2 (28 and 3.7 kg s-1, respectively), HCl (9.6 and 1.3 kg s-1, respectively), HF (4.5 and 0.3 kg s-1, respectively) and near-source sulfate aerosol (0.5 and 0.1 kg s-1, respectively). Aerosol plumes are characterized by particle number fluxes (0.08-4.0 μm radius) of ∼1017...
