The surface mass balance scheme dEBM (diurnal Energy Balance Model) provides a novel, computationally inexpensive interface between the atmosphere and land ice for Earth system modeling.

Here are the main findings:
- The dEBM is particularly suitable for Earth system modeling on multi-millennial timescales as it accounts for changes in the Earth’s orbit and atmospheric greenhouse gas concentration.
- Realistic simulations of the Greenland Ice Sheet covering several millennia require a representation of surface melting driving ice loss. Since involved processes are complex, the dEBM computes this surface melting from primary forces.
- Hence, the model reproduces intensified melting during the warmer mid-Holocene period 6000 years ago, when astronomical settings of the earth caused higher summer temperatures.
