    Description:
      Abstract:
        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.
      Purpose: Presentation of results of model ICE4G.
      Supplemental_Information:
        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.
