This ORDA repository location contains estimated contemporary and future 
surface relief, depression volume and surface lake volume maps of the Greenland Ice Sheet. 

The maps are produced for 3 time slices which each use different 
greenhouse gas emission scenarios (i.e. historical or Representative Concentration Pathway (RCP)):

Two separate versions are produced for future estimations:
1. incorporating the effects the changing surface mass balance
2. incorporating the effects of both the changing surface mass balance 
and the changing ice sheet thickness and flow velocity

These datasets are the key outputs of our manuscript entitled: 
"Enhanced formation of surface lakes in the interior of the Greenland Ice Sheet after 2100 due to growing surface relief".
