Since 2002, the GRACE program has provided a large amount of high-precision data, which can be used to detect temporal Breast Pump Accessories gravity variations related to global mass re-distribution inside the fluid envelop of the surface of the Earth.In order to make use of the GRACE data to investigate earthquake-related gravity changes in China, we first studied the degree variances of the monthly GRACE gravity field models, and then applied Reachers decor-relation and Gaussian smoothing method to obtain seasonal gravity changes in China.By deducting the multi-year mean seasonal variations from the seasonal maps, we found some earthquake-related gravity anomalies.
