Simulations of millennial-scale climate variability influence on Northern Hemisphere ice sheet mean state, supplement to: Niu, Lu; Lohmann, Gerrit; Gowan, Evan J (2019): Climate noise influences ice sheet mean state. Geophysical Research Letters
This study mainly focuses on the millennial-scale climate variability influence on the Northern Hemisphere ice sheet evolution during the past glacial-interglacial cycles. We use the 3D thermodynamical Parallel Ice Sheet Model (PISM) version 0.7.3 to simulate the ice sheets. An index method is used...
