Abstract We collect and sort the data of 10 phases of mobile gravity re-measurement from 2016 to 2020 in Hainan. We use the primary term scale coefficient calibrated by gravimeters sharing institutions to adjust the re-measured data of each period. The results show that the gravity field of Hainan has changed significantly during the period 2016-09~2017-05, 2017-05~10, 2018-05~10. Based on the primary term scale coefficient of the instrument in the first period of 2016, we use the gravity differential method to correct the primary term scale coefficient. We then reprocess the quasi-stable adjustment. The results show that since 2016, the differential gravity field of Hainan has changed relatively smoothly, and the change of the gravity field is basically within 30 μGal. The significant gravity field anomalies of Hainan disappear. So, if we use the gravity differential method to correct the primary term scale coefficient, we can effectively reduce the gravity field change error caused by the primary term scale coefficient error.
