SO2 flux of VILLARRICA volcano, from the NOVAC data-base

This data-set presents volcanic gas emission data from NOVAC, the global Network for Observation of Volcanic and Atmospheric Change. For each volcano, data from one or several NOVAC Scanning mini-DOAS instruments are combined with meteorological information to derive daily statistics of total SO2 emission from the volcano. Different versions of the data exist, depending on the algorithms and meteorological information used in the evaluations. Data is kindly made publicly available by the volcanological observatories and institutions responsible for data collection and evaluation, on the condition that credit is given according to the NOVAC Data Use Agreement.
