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 Onsala station (code OS, instrument GWR OSG 054) was established in 2009 thanks to the financial support of the Committee for Infrastructure of the Swedish Research Council, until 2021, and of the Swedish geodetic survey Lantmäteriet since 2021. Continuous time-varying gravity and atmospheric pressure data from OS are integrated in the IGETS data base hosted by ISDC (Information System and Data Centre) at GFZ. The OS station (longitude: 11.9266 E; latitude: 57.3858 N and elevation: 7.93 m) is located at the Onsala Space Observatory, south of Gothenbourg, a well instrumented site for geodetic and meteorological studies (https://www.chalmers.se/en/researchinfrastructure/oso/Pages/default.aspx).
An air-circulation system controls the humidity and temperature in the gravimeter house and there are 3 pillars available. Absolute gravity measurements are done every year by Lantmäteriet.
- The time series of gravity and barometric pressure started in July 2009 and is going on.
- The time sampling of the raw gravity and barometric pressure data of IGETS Level 1 is 1 minute.
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).
Rainfall data are also provided as auxiliary data to IGETS database. OS data are used in conjunction with projects of the Nordic Geodetic Commission (NKG) - Working Group for Geodynamics (https://www.nordicgeodeticcommission.com/working-group-of-geodynamics/). Interactive graphs are available at https://lab3.oso.chalmers.se/wx/gravimeter_data/
