Zusammenfassung: |
Presently, modern spring gravimeters are the most flexible, technically simple, and comparatively cheap solution for recordings over extended time periods in contrast to superconducting gravimeters. We investigate the accuracy of the state-of-the-art spring gravimeters Micor-g LaCoste gPhone-98 and ZLS Burris Gravity Meter B-64 of the Institut für Erdmessung (IfE). With both instruments gravity was recorded for periods of several months at five stations with high and low microseismic noise. Simultaneous measurements with both instruments as well as the parallel recording of the ZLS Burris gravimeter with the GWR Instruments Observatory Superconducting Gravimeter OSG-054 in Onsala (Sweden) are investigated. Tidal analysis is used to assess the quality of the time series. Diurnal and semi-diurnal amplitude factors agree at the level of 1 per mille and better from recordings of Burris and OSG gravimeters in Onsala. The final publication is available at Springer via https://doi.org/10.1007/1345_2015_29
