Fig. S4. Non-linear ice-sheet mass variability for EAIS basins . Time series of mass change after the subtraction of the linear and periodic terms from the multiple linear regression for each EAIS basin (crosses with 95% confidence intervals). The SAMΣ and Niño3.4Σ components of the model are shown separately and as a sum (orange, purple, and black lines respectively). The shaded area shows the 95% confidence interval for the sum of the SAMΣ and Niño3.4Σ terms. In-figure text shows the percentage of the partial variance explained (R2) by SAMΣ, Niño3.4Σor both terms (see Methods). Text color corresponds to the line color. Basin numbers are shown on Fig. S3.
