This grid summarises the processing which has been carried out on the ice surface/thickness configuration dataset.

Value Description: 0 Ocean, 1 Ramp surface, 2 JLB/JAG surface grounded, 3 JLB/JAG surface floating, 4 Ice shelf areas not consistent with JLB/JAG surface (firn correction greater than surface), 5 Ice shelf thickness join smoothed and replaced if less than original, 6 Shelf thickness changed because less resulting surface less than firn correction (post smoothing), 7 Missing/negative grounded ice thickness smoothed, 8 Missing/negative grounded ice thickness replaced with 50m, 9 Ice free areas, ice thickness set to zero, 10 Non-grounded ice: bed elevation changed, ice thickness unchanged, surface not consistent with JLB/JAG, 11 Non-grounded ice: bed 'and' ice thickness changed, surface is consistent with JLB/JAG
