Title

InitMIP-Greenland experiments with the ice sheet model SICOPOLIS

Abstract

SICOPOLIS (SImulation COde for POLythermal Ice Sheets) is a three-dimensional, dynamic/thermodynamic ice-sheet model that can be used for simulating problems of past, present or future glaciation of the Greenland ice sheet, the Antarctic ice sheet and other land-ice bodies (www.sicopolis.net). Here, it is applied to the Greenland ice sheet with a horizontal resolution of 5 km to conduct the InitMIP-Greenland experiments. The objective of InitMIP-Greenland is to compare, evaluate, and improve the initialization techniques used in the ice sheet modelling community, and to estimate the associated uncertainties in modelled mass changes.

Abstract (Brief description of the experiment contents (initial conditions, boundary conditions, etc.))
InitMIP-Greenland consists of three experiments: (1) 'init': initial present-day state of the ice sheet, (2) 'ctrl': 100-year forward simulation with constant-climate forcing, (3) 'asmb': 100-year forward simulation with a large perturbation (prescribed surface mass balance anomaly) that mimics roughly an upper-end climate-change scenario like RCP8.5. We carried out these experiments with two different set-ups, labelled in the data set as 'ILTS_SICOPOLIS' and 'ILTSPIK_SICOPOLIS', respectively. For each set-up and each experiment, a range of ice-dynamic variables are available: ice thickness, surface and bed topographies, surface and basal mass balance, x-, y- and z-components of the surface, basal and depth-averaged flow velocity etc. The total size of the data set is approximately 0.5 GB.
