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 Strasbourg station (code ST) was established in 1996 thanks to the financial support of INSU-CNRS France. Continuous time-varying gravity and atmospheric pressure data from ST are integrated in the IGETS data base hosted by ISDC (Information System and Data Centre) at GFZ.

The ST station is the unique permanent station in France belonging to the geophysical observatories funded by INSU-CNRS. The operation and maintenance of the ST instrumentation is done by staff at EOST/IPG Strasbourg.

The ST station is located in an old bunker built in 1875 (called J9) which is 10 km away from Strasbourg city (longitude: 7.684 E, latitude: 46.622 N, height above MSL: 180 m). The area is located in the sediments of the Rhine graben and the local environment is agricultural with no close industry. The observatory is partly underground with a loess layer of about 1 m thick above it.

An air-circulation system controls the humidity and temperature in all the rooms inside the bunker and there are about 10 pillars available. One room is dedicated to the absolute gravity measurements done regularly with FG5#206 operated by EOST Strasbourg. SG C026 manufactured by GWR Instruments was installed in 1996 and stopped in November 2018. The new SG iOSG#23 was installed in February 2016. Both meters ran side by side between February 2016 and November 2018 in order to perform an intercomparison in terms of noise level (Rosat & Hinderer 2018) and instrumental drift.

The time series of gravity and barometric pressure from SG C026 starts in July 1996 and ends in November 2018. The time series of gravity and barometric pressure from iOSG#23 starts in February 2016 and is going on.

The time sampling of the raw gravity and barometric pressure data of IGETS Level 1 is 1 minute. Raw data with a time sampling of 1 second will be provided additionally on the seismological IRIS Data Management Center (http://ds.iris.edu/mda/SG/ST).

For a detailed description of the IGETS data base and the provided files see Voigt et al. (2016, http://doi.org/10.2312/GFZ.b103-16087).

In addition, ST station is equipped with auxiliary data supporting the interpretation of the SG measurements, which is, however, not provided in the IGETS data base due to complexity. These are a local network of hydrological and meteorological sensors as well as a permanent GNSS (Global Navigation Satellite Systems) station belonging to the RENAG network (http://renag.resif.fr/).

      • Summary
        • 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 Strasbourg station (code ST) was established in 1996 thanks to the financial support of INSU-CNRS France. Continuous time-varying gravity and atmospheric pressure data from ST are integrated in the IGETS data base hosted by ISDC (Information System and Data Centre) at GFZ. The ST station is the unique permanent station in France belonging to the geophysical observatories funded by INSU-CNRS. The operation and maintenance of the ST instrumentation is done by staff at EOST/IPG Strasbourg. The ST station is located in an old bunker built in 1875 (called J9) which is 10 km away from Strasbourg city (longitude: 7.684 E, latitude: 46.622 N, height above MSL: 180 m). The area is located in the sediments of the Rhine graben and the local environment is agricultural with no close industry. The observatory is partly underground with a loess layer of about 1 m thick above it. An air-circulation system controls the humidity and temperature in all the rooms inside the bunker and there are about 10 pillars available. One room is dedicated to the absolute gravity measurements done regularly with FG5#206 operated by EOST Strasbourg. SG C026 manufactured by GWR Instruments was installed in 1996 and stopped in November 2018. The new SG iOSG#23 was installed in February 2016. Both meters ran side by side between February 2016 and November 2018 in order to perform an intercomparison in terms of noise level (Rosat & Hinderer 2018) and instrumental drift. The time series of gravity and barometric pressure from SG C026 starts in July 1996 and ends in November 2018. The time series of gravity and barometric pressure from iOSG#23 starts in February 2016 and is going on. The time sampling of the raw gravity and barometric pressure data of IGETS Level 1 is 1 minute. Raw data with a time sampling of 1 second will be provided additionally on the seismological IRIS Data Management Center (http://ds.iris.edu/mda/SG/ST). For a detailed description of the IGETS data base and the provided files see Voigt et al. (2016, http://doi.org/10.2312/GFZ.b103-16087). In addition, ST station is equipped with auxiliary data supporting the interpretation of the SG measurements, which is, however, not provided in the IGETS data base due to complexity. These are a local network of hydrological and meteorological sensors as well as a permanent GNSS (Global Navigation Satellite Systems) station belonging to the RENAG network (http://renag.resif.fr/).
