Fig. 7

Spatial distribution of normalized weights (dividing the weights of each model by the sum of weights of all models in combination grid by grid) for each model in the combination of SHC solutions using grid-wise weighting. (a–e) represent weights corresponding to the GRACE SHC solutions of AIUB, CSR, GFZ, ITSG, and JPL. For ease of visualization and comparison, the weights corresponding to individual models were averaged over time from March 2003 to March 2014.
