Antarctic Ice Sheet, Cryosat-2,Satellite Altimetry,DEM, Crossover Adjustment,Kriging Interpolation, Intersection
2018/5/15
In this paper, the Cryosat-2 altimeter data distributed by the ESA, and these data are processed to extract the information of the elevation change of the Antarctic ice sheet from 2010 to 2017. Firstl...
Mass-conserving subglacial hydrology in the Parallel Ice Sheet Model version 0.6
Parallel Ice Sheet Model subglacial hydrology
2015/8/6
We describe and test a two-horizontal-dimension
subglacial hydrology model which combines till with a distributed system of water-filled, linked cavities which open
through sliding and close t...
A few decades ago, Antarctic ice sheets were expected to grow as the
atmosphere warmed and increasing poleward moisture transport added snowfall
to regions that would remain below freezing year-ro...
Comparing a thermo-mechanical Weichselian Ice Sheet reconstruction to reconstructions based on the sea level equation: aspects of ice configurations and glacial isostatic adjustment
thermo-mechanical Weichselian Ice Sheet reconstruction to reconstructions sea level equation ice configurations glacial isostatic adjustment
2015/1/6
In this study we compare a recent reconstruction of the Weichselian Ice Sheet as simulated by the University of Maine ice sheet model (UMISM) to two reconstructions commonly used in glacial isostatic ...
Future Antarctic bed topography and its implications for ice sheet dynamics
Future Antarctic bed topography ice sheet dynamics
2015/1/6
The Antarctic bedrock is evolving as the solid Earth responds to the past and ongoing evolution of the ice sheet. A recently improved ice loading history suggests that the Antarctic Ice Sheet (AIS) ha...
Adding a dynamical cryosphere to iLOVECLIM (version 1.0): coupling with the GRISLI ice-sheet model
Adding a dynamical cryosphere iLOVECLIM GRISLI ice-sheet model
2014/12/19
We present a coupling approach to and the first results of the GRISLI ice-sheet model within the iLOVECLIM-coupled climate model. The climate component is a relatively low-resolution earth system mode...

Formulation calibration validation DAIS model simple Antarctic ice sheet model sensitive sea level ocean subsurface temperature
2014/12/19
The DCESS (Danish Center for Earth System Science) Antarctic Ice Sheet (DAIS) model is presented. Model hindcasts of Antarctic ice sheet (AIS) sea level equivalent are forced by reconstructed Antarcti...
