Please note, this page is a work in progress and is not ready for discussion yet.
Please use the Discussion section below to specifically comment on the choice of ice sheet reconstructions for the core experiment.
For the core experiment, there is a choice of two global ice sheet reconstructions:
Please one of these reconstructions for your Last Glacial Maximum (LGM) experiment, as per the LGM working group requirements, and continue to use the same reconstruction through the transient last deglaciation core simulation.
Those groups that are able may wish to carry out two simulations; one with each ice sheet reconstruction.
The ice mask in this reconstruction is fractional. For the purpose of the animations (below), we have used > 80 % ice cover per grid cell.1)
The information in this section was provided directly by Dick Peltier et al., October 2014:
Time dependent ice-equivalent contribution to eustatic sea level rise [relatice to present day] from each of the primary geographical regions from which grounded ice loss occurred during the [last] deglaciation process. 2)
|Ice-equivalent contribution to eustatic sea level rise (m) 3)|
|Final ICE-4G||ICE-5G v1.2||ICE6G_C|
|N. America (incl. Inuit area)||54.92||83.71||87.01|
|Greenland & Iceland||5.43||2.45||2.39|
|N. America (incl. Innuit area)||64.24||81.47||78.82|
|Greenland & Iceland||6.38||2.49||2.41|
The ice mask in this reconstruction is based on 100 % ice or 0 % ice.4)
