Figure 4.
Negative and positive SMB of all models (a) and for the marked inset excluding outliers (b). Diamonds, squares and triangles in (b) give partitioning from average 1979–2000 regional climate model simulations (van Angelen et al., 2014; Fettweis et al., 2017, Noël et al., 2016) with masking to the ice-covered region (grey) and to the ice sheet proper (IS, black) according to the mask of Rastner et al. (2012). Compare symbol colour to identify individual models with Figures 3–5. Data are available in supplementary Table S1.
