WHAT IS IN THIS REPOSITORY

This repository contains all the environmental data collected for site characterization activities
for the ET Sardinia candidate site.

The data comprehend:

- seismic data

• from permanent network (broadband)
• from temporary arrays (broadband and geophones)

- weather data

• wind speed
• temperature
• barometric pressure
• humidity
• rain

- microphones
- magnetometers
- seismic stations metadata

NOTICE ABOUT METADATA:

Metadata of all broadband seismometers from both permament and temporary (arrays) installations
are stored in /etrepo/data-sites/sosenattos/ETSCOPE/current_metadata/cjunkk_ETScope.xml

Metadata of geophones arrays are not available on xml files.
Please get in touch with Matteo Di Giovanni (matteo.digiovanni@uniroma1.it) or Soumen Koley (soumen.koley@gssi.it)
for further instructions about deconvolution of geophone data or use the functions and parameters provided in geop_decon.py.

HOW TO ACCESS DATA

Data are stored on MSeed files following the SDS organization.
Python's module ObsPy provides all the tools to easily read the data.
Please go to https://docs.obspy.org for documentations and tutorials.

PERMANENT NETWORK

Root directory for the permament network is /etrepo/data-sites/sosenattos/ETSCOPE/
Data are divided per year in folders (see SDS organization)

- Network: ET
- Stations: SOE0 (Sos Enattos surface station - depth 0m)
SOE1 (Sos Enattos underground station - depth 84m)
SOE2 (Sos Enattos underground station - depth 111m)
SOE2T (test station colocated with SOE2)
SOE3 (Sos Enattos underground station - depth 160m)
P2 (proposed vertex)
P3 (proposed vertex)

- Location: stations have no location code except for P2 and P3
00: surface sensor (depth 0m)

ARRAYS DEPLOYED BY GSSI

- Network: GSSI_P2/GSSI_P3/GSSI_BR
- Stations: Array deployed at P2 from September, 13 2021 until October 2021. Sensors were left there until battery discharge, so total number of days may change depending on the sensor. All sensors are 5 Hz geophones. No inventory file is available, for response removal please contact matteo.digiovanni@uniroma1.it or soumen.koley@gssi.it or use the functions and parameters provided in geop_decon.py
