Infrasound array data recorded in July-August, 2019, at Mt. Etna (Italy) during the VOSSIA field experiment

We present infrasound data recorded by two infrasound arrays installed at Mt. Etna (Italy) within the framework of the VOSSIA (Volcanic emissions analysis through Seismic and Infrasound Advanced monitoring) project. VOSSIA was supported by the Trans-National Access component of the EUROVOLC project (European Network of Observatories and Research Infrastructures for Volcanology, EU Horizon 2020 Research Infrastructure Project grant No 731070). This data repository includes continuous raw waveforms recorded by two 6-element, small-aperture, infrasound arrays during July-August, 2019. The arrays, ENEA and ENCR, were installed on Mt. Etna in proximity of the summit Nord East and South East craters, respectively. ENEA was equipped with Chaparral M60 sensors (http://chaparralphysics.com/specs/specs_model60UHP.pdf), while IST2018 microphones (https://doi.org/10.1016/j.jvolgeores.2019.106668) were installed at ENCR. Data at both arrays were recorded with a sampling frequency of 100 Hz and 24-bit resolution using DiGOS Datacube³ digitizers (https://digos.eu/seismology-and-cubes). Waveform data are provided as day-long files in MSEED format (https://ds.iris.edu/ds/nodes/dmc/data/formats/). We also provide metadata including: 1) Station coordinates (.csv file station_coords.csv); 2) Instrument_response.rar: Instrument response information in different formats (individual RESP files, SEED DATALESS, xlm DATALESS)本数据集呈现了依托VOSSIA项目（Volcanic emissions analysis through Seismic and Infrasound Advanced monitoring，即基于地震与次声波先进监测的火山排放物分析）框架，安装于意大利埃特纳火山（Mt. Etna）的两套次声波（infrasound）阵列所采集的次声波数据。VOSSIA项目获得EUROVOLC项目跨国访问计划（Trans-National Access）的支持，EUROVOLC项目全称为欧洲火山学观测台与研究基础设施网络（European Network of Observatories and Research Infrastructures for Volcanology），属于欧盟地平线2020（Horizon 2020）研究基础设施项目，资助编号为731070。本数据集包含2019年7月至8月期间，由两套6单元小口径次声波阵列采集的连续原始波形数据。两套阵列分别为ENEA与ENCR，分别安装在埃特纳火山的东北火山口与东南火山口附近区域。ENEA阵列配备Chaparral M60传感器（详见http://chaparralphysics.com/specs/specs_model60UHP.pdf），ENCR阵列则安装了IST2018型麦克风（详见https://doi.org/10.1016/j.jvolgeores.2019.106668）。两套阵列的数据均采用DiGOS Datacube³数字化仪（详见https://digos.eu/seismology-and-cubes）采集，采样率为100 Hz，分辨率为24位。波形数据以单日时长文件的形式提供，格式为MSEED（详见https://ds.iris.edu/ds/nodes/dmc/data/formats/）。本数据集同时提供如下元数据：1）台站坐标信息（存储为station_coords.csv的CSV文件）；2）Instrument_response.rar：包含多种格式的仪器响应数据（单RESP文件、SEED DATALESS格式、xlm DATALESS格式）。
