Abstract: Volcanic gas ratios in the plume of White Island Volcano (New Zealand), acquired using a Multi-GAS of the DECADE network. Data are reported for the bulk plume released by the summit crater. All ratios are expressed on molar basis. Note that this file includes only processed data showing ratios of gases. All raw data is available in a separate file entitled "Volcanic_gas_plume_data_from_White_Island_Volcano-Raw_data" that can be downloaded from the same web location as this file.
