gPhone data

Gravity residuals (in microgales) after processing the raw gPhone observation data.The gPhone data were preprocessed using the Tsoft software, including the identification and correction of anomalous signals such as spikes, steps, and discontinuities, as well as corrections for major geophysical effects (e.g., tides and atmospheric pressure loading). Instrumental drift was subsequently removed using a piecewise fitting approach, and the resulting gravity residuals primarily reflect hydrological mass variations in the vicinity of the station during the observation period.本数据集为经处理原始gPhone观测数据后得到的重力残差，单位为微伽（microgales）。研究人员采用Tsoft软件对gPhone观测数据进行预处理，具体包括尖峰、阶跃与间断等异常信号的识别与校正，以及潮汐、大气压力负荷等主要地球物理效应的校正；随后通过分段拟合方法移除仪器漂移，最终得到的重力残差主要反映观测时段内测站周边的水文质量变化。
