Volcanic gas plume data from Etna Volcano (Italy)

Volcanic gas CO2/SO2 ratios in the plume of Etna Volcano (2006-2011 period), acquired using a Multi-GAS of the INGV-PA monitoring network. Data are reported for the bulk plume released by the Central Crater. All ratios are expressed on molar basis. Note that this file includes only processed data showing ratios of gases (calculated using the Ratiocalc software).埃特纳火山（Etna Volcano）火山羽流中的火山气体CO₂/SO₂比值（2006-2011年时段），采用INGV-PA监测网络的Multi-GAS设备采集获取。本数据集针对中央火山口（Central Crater）释放的整体火山羽流进行数据记录，所有比值均以摩尔基准进行表述。请注意，本文件仅包含经Ratiocalc软件计算得到的气体比值处理后数据。
