LIDO 1 - Gravimeter dataset


Instrument: IFSI (INAF) Prototype #2
Investigator: Mariagrazia De Caro (INGV)
Observatory: GEOSTAR

Citation: De Caro, Mariagrazia. (2009). Gravimeter dataset (IFSI (INAF) Prototype #2 @ 1 Hz) from INGV/GEOSTAR seafloor platform during ESONET-NOE-LIDO project in Iberian Margin site (Gulf of Cadiz), part of EMSO network.

Abstract: The dataset contains relative values of gravity acceleration measured by a prototype of gravity meter, with sensitivity close to 10^-9 g/sqrt(Hz) in the range from 10^-5 to about 1 Hz. The prototype was developed at the Istituto di Fisica dello Spazio Interplanetario (IFSI) of the National Institute of Astro-Physics (INAF). The gravimeter acquired with a sampling rate of 1 Hz.

Purpose: The instrument performs measurements of the Earth gravity acceleration due to low ground movements (tides) and fast ground movements (seismic wave propagation).

Quality of data: Systematic noise lasting for 5 seconds is present at start of each daily file due to the midnight clock synchronisation. The 247 daily text files are stored in a folder of 749 MB. In general the gravimetric data shows a good recording quality.
