GPlaSim Glacier Model Adiv Paradise -- 07.14.2017 Since we can grow our own glaciers and ice sheets, you don't want PlaSim's default prescribed ice-related elevation for Antarctica and Greenland. The surface file in this folder has their elevations decreased by ~few km, so they're still above sea level, but not by that much. If you put 3 km of ice on them, they'll be back to normal elevation.
