Abstract:Based on 8 glacial isostatic adjustment(GIA) models commonly used in the world, we calculate the global mass change trends from 2005 to 2014 using GRACE data corrected by GIA. When correcting in Antarctic region, the correction values of the three models: ICE-6G_C, ICE-6G_D and IJ05, are similar. When correcting the global ocean mass changes, the mean value of the impact of different correction models on global ocean mass changes is below -2.0 mm/a. We contrast the contribution of land water and ice sheet to the trend of ocean mass changes, and combining satellite altimetry and Argo data to further verify that the Paulson07, Geruo13 and ICE-6G_D models are relatively suitable for global ocean mass correction. Integrating the entire land and ocean, ICE-6G_D model is more suitable for adjusting the global mass change.
