Emission rate of SO2 from Villarrica volcano for the period 2014-11-24 to 2016-02-11. This dataset contains individual SO2 flux measurements obtained from scanning DOAS instruments part of the NOVAC network, operated by SERNAGEOMIN (Chile), and daily statistics. Data has been processed with the NOVAC batch processing software, using meteorological data from the ECMWF ERA interim analysis database (0.125/0.125 deg, 6 h) interpolated at the volcano summit coordinates for the time of each measurement. Plume height and direction is obtained by triangulation of two scan measurements when possible. Also including daily statistics. Raw data can be accessed by contacting the authors. Data submitted within the DECADE/DCO project.
