Basin-scale comparison presenting the RMSE values of the respective TWSA solutions between July 2004 and June 2010 for 120 watersheds. The filled circles of the error bars show the median of the RMSE values based on 1,000 samples, and the upper and lower caps represent the confidence intervals. The ascending basin number indicates the descending area size, e.g., basin 001 refers to the Amazon Basin and 120 to the Severn River basin. The grey rectangles indicate the basins at which the RMSE values of GRACE solutions are equal to or larger than the standard deviation of the observations.
