Northern Hemisphere ice sheets simulated by the GRISLI model at 18 ka BP, prior to Heinrich event 1, in terms of ice thickness (a) , ice velocities (b) and subsurface (550–1050 m)
Dashed and dotted blue lines correspond respectively to the raw and to the downscaled CNRM-CM5.1 simulations, red and green solid lines correspond respectively to Crocus
The SMB anomaly projection for k = a/b =− 1 as well as the cumulated sea level rises equivalent are shown in Fig. This record surface mass loss rate is likely to become com- mon at
Consequences of a warmer climate on the Greenland Ice Sheet (GrIS) mass balance will be a thickening inland, due to increased solid precipitation, and a thinning at the GrIS
We apply a new parameterisation of the Greenland ice sheet (GrIS) feedback between surface mass balance (SMB: the sum of surface accumulation and surface ablation) and surface
Our quantitative assessment of ice thickness accuracy uses the same BEDMAP data set employed earlier to assess el- evation accuracy. However, unlike those elevation compar- isons,
The mean values and uncertainties of snow depth and ice and snow densities, determined for FY ice and MY ice, were used to calculate the total error in ice thickness retrieval
the lower ablation zone albedo returned to near-normal values in July 2010, since high melt occurs here every year, in the higher regions of the ablation zone it remained at least
