Postglacial rebound in Fennoscandia causes striking trends in gravity measurements of the area. We present time series of absolute gravity data collected between 1976 and 2019 on 12 stations in Finland with different types of instruments. First, we determine the trends at each station and analyse the effect of the instrument types. We estimate, for example, an offset of 6.8 μgal for the JILAg-5 instrument with respect to the FG5-type instruments. Applying the offsets in the trend analysis strengthens the trends being in good agreement with the NKG2016LU_gdot model of gravity change. Trends of seven stations were found robust and were used to analyse the stabilization of the trends in time and to determine the relationship between gravity change rates and land uplift rates as measured with global navigation satellite systems (GNSS) as well as from the NKG2016LU_abs land uplift model. Trends calculated from combined and offset-corrected measurements of JILAg-5- and FG5-type instruments stabilized in 15 to 20 years and at some stations even faster. The trends of FG5-type instrument data alone stabilized generally within 10 years. The ratio between gravity change rates and vertical rates from different data sets yields values between − 0.206 ± 0.017 and − 0.227 ± 0.024 µGal/mm and axis intercept values between 0.248 ± 0.089 and 0.335 ± 0.136 µGal/yr. These values are larger than previous estimates for Fennoscandia.

芬诺斯坎迪亚的冰川后回弹引起该地区重力测量的惊人趋势。我们介绍了1976年至2019年在芬兰的12个站点上使用不同类型的仪器收集的绝对重力数据的时间序列。首先，我们确定每个站点的趋势并分析仪器类型的影响。例如，我们估计JILAg-5仪器相对于FG5型仪器的偏移为6.8μgal。在趋势分析中应用偏移可以增强趋势，使其与重力变化的NKG2016LU_gdot模型完全一致。发现七个台站的趋势很稳健，并被用来分析时间趋势的稳定性，并确定重力变化率与地面抬升率之间的关系，这是通过全球导航卫星系统（GNSS）以及NKG2016LU_abs地面抬升测量的模型。通过对JILAg-5-和FG5型仪器进行组合和偏移校正后的测量结果得出的趋势稳定了15至20年，并且在某些站点甚至更快。仅FG5型仪器数据的趋势一般在10年内就稳定了。来自不同数据集的重力变化率和垂直率之间的比率得出的值介于-0.206±0.017和-0.227±0.024 µGal / mm之间，而轴截距值介于0.248±0.089和0.335±0.136 µGal / yr之间。这些值大于以前对芬诺斯堪迪亚的估计。
