Absolute Gravity Measurements at the Alpine Research Centre in Obergurl (Austria) in September 2021

This report contains the results of absolute gravity measurements carried out at Alpine Research Centre (University of Innsbruck) in Obergurgl. The measurements took place on the pier 0-173-02 (Figure 1) in September 2021.

The absolute gravimeter FG5X#216 was operated by Olivier Francis and Raquel Navarro Buendía from the University of Luxembourg.

The measurements are part of an on-going research collaboration between the Geophysics Laboratory of the University of Luxembourg and Christian Ullrich and Helmut Titz from the Bundesamt für Eich- und Vermessungswesen (BEV, Federal Office of Metrology and Surveying) in Vienna, Austria.

It is the fourth time we measured at this site. Measurements were previously performed in June, September 2018 and 2019. Due to the COVID-19 pandemic, we could not take measurements in 2020.
