In the version of the article initially published, we referred to the surface mass balance module of PISM as dEBM. However, the surface mass balance module introduced by Zeitz et al.1 and used in PISM is a modified version of the full dEBM scheme introduced by Krebs-Kanzow et al.2,3. To make this distinction clearer, we now clearly state that we use dEBM-simple and added an additional explanation in the Methods. We thank Uta Krebs-Kanzow for pointing this out.
