This data set consists of the results of the model ICE-4G, topography and ice cover data files. Data consist of topographical heights at 1 Kyr intervals since the last glacial maximum and ice-cover data at 1 Kyr intervals since the last glacial maximum. Topography is specified in metres. However in order to present a dataset in positive integer format, 10000 has been added. i.e if the data in this dataset is called itopog then true_topog = itopog - 10000 true_topog has values within the range [-9300,7200] metres. The data are presented on a 1 degree latitude by 1 degree longitude grid. Data starting at (-179.5,+89.5), 180 rows of 360 points along a line of constant latitude. In some areas, the ice-cover data indicates that there is ice while the topographic height is negative indicating that the region is below sealevel. In these cases, it should be assumed that the area is ice-covered. Either the region is not inundated or the ice is floating.
