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)
