Abstract

The International Geodynamics and Earth Tide Service (IGETS) was established in 2015 by the International Association of Geodesy. IGETS continues the activities of the Global Geodynamics Project (GGP) between 1997 and 2015 to provide support to geodetic and geophysical research activities using superconducting gravimeter (SG) data within the context of an international network.

As part of this network, the Rustrel station (code RU) was established in 2015 thanks to the financial support of the EQUIPEX MIGA (Matter wave-laser based Interferometer Gravitation Antenna) ANR-11-EQPX-0028 and by the European FEDER 2006-2013 “PFM LSBB - Développement des qualités environnementales du LSBB”. Continuous time-varying gravity and atmospheric pressure data from RU are integrated in the IGETS data base hosted by ISDC (Information System and Data Centre) at GFZ.

The operation and maintenance of the RU instrumentation is done by staff at EOST/IPG Strasbourg. The RU station is located about 500 m beneath the surface in the underground research laboratory of the LSBB (« Laboratoire Souterrain à Bas Bruit ») built in 1997. The LSBB is located within the Regional Natural Park of Luberon (longitude: 5.4837 E, latitude: 43.9411 N, height above MSL: 499.3 m).

The LSBB gallery is located in the unsaturated zone of the Fontaine de Vaucluse karst hydrosystem. There is no industry around the site so the anthropogenic noise is very low. The time series of gravity and barometric pressure from iOSG-24 starts in October 2015 and is going on. The time sampling of the raw gravity and barometric pressure data of IGETS Level 1 is 1 minute.
