1st Workshop on the International Geodynamics and Earth Tide Service (IGETS)

18-20 June 2018, Potsdam (Germany)

IGETS was accepted as an IAG service at the IUGG General Assembly 2015 in Prague. The primary objective of the International Geodynamics and Earth Tide Service (IGETS) is to provide a service to monitor temporal variations of the Earth gravity field through long-term records from ground gravimeters, tiltmeters, strainmeters and other geodynamic sensors. IGETS continues the activities of the Global Geodynamic Project (GGP) to provide support to geodetic and geophysical research activities using superconducting gravimeter data.

The IGETS business meetings held in Trieste (2016), Vienna and Kobe (2017) showed progress in establishing the service, but also the need of a workshop on the IGETS products and stations as well as their large variety of applications. The first IGETS workshop is held from 18 to 20 June 2018 at Helmholtz Centre Potsdam - GFZ German Research Centre for Geosciences, Telegrafenberg, Potsdam, Germany.

The workshop consists of three sessions. The first session is dedicated to station reports. Representatives of IGETS station operators are free to define the focus of their individual contributions, which could include recent changes, performance assessments as well as planned upgrades of instruments or facilities. All IGETS station operators are cordially invited to participate and to contribute to this session.

The second session focuses on the IGETS products from level 1 to 3 and the IGETS database with contributions from the corresponding representatives of IGETS. These include the production of level 2 and 3 data, aspects of preprocessing, documentation of step correction and the provision of calibration files and real-time data analysis. Recent developments in tidal analysis are presented. There will be room to discuss links to seismological networks and the absolute gravity database.

The third session aims to improve the visibility of the IGETS products by demonstrating the large variety of applications reaching from hydrological and geothermal signals to estimates of the rheology of the Earth. This session seeks contributions from users of IGETS products and other continuously operated geodynamic sensors included in the IGETS database. Specifically, operators and users of iGrav superconducting gravimeters not currently part of IGETS are encouraged to contribute.

Please send the title and a short abstract of your contribution to session 1 or 3 to the local organizing committee by 16 April 2018 (extended). The workshop is free of charge. However, a registration is required.
