Abstract:We processed the gravity observation data of total solar eclipse, which took place along Yangtze River on July 22, 2009. The observations of one GWR superconducting gravimeter and three spring gravimeters were chosen to processed tide analysis and pressure corrections. The observation data of superconducting gravimeter and air pressure had a negative correlation, but a good correlation between the residual time series of the three spring gravimeters, the noise level was within the normal accuracy range. The result showed that there was no substantial gravity anomaly during the total solar eclipse no matter the superconducting gravimeter or the spring gravimeter.
