主 题：gravity gravity change heavy rain gravimeter gPhone
摘 要：The short-term effect of heavy rainfall on gPhone gravimeter observation at Zhengzhou seismic station is investigated. According to the observation data during 2021-07-17～07-20， the corrected gravity residual reflects the gravimetric response caused by heavy rainfall. The observed gravity change is dominated by the local effect considering topographic effect on gravity. The deduced water depth near the observation station is about 300 mm.
