Volcanic gas plume data from Lastarria Volcano (Chile)

On 28 November 2012, we used the MultiGAS (GPS-synchronized) to characterize the chemical structure and heterogeneity of Lastarria’s bottom fumarolic field. The plume was also measured in a fixed point for several hours on 29-30 November 2012. Note that this file includes only processed data showing ratios of gases (calculated using the Ratiocalc software). SO2 gas fluxes have been obtained by deploying portable scanning DOAS (Differential Optical Absorption Spectroscopy) instruments. All raw data is available in a separate file entitled \"Volcanic gas plume data from Lastarria Volcano - Raw data\" that can be downloaded from the same web location as this file.
