| Summary: | A set of land-atmosphere coupled global climate model simulations were performed to investigate the sensitivity of the permafrost dynamics and the soil settings to the subsurface hydro-thermal states and to examine the impacts on the hydro-climate above the surface. c5s0 (conventional land process scheme; conventional soil property values; 5-layer 4m soil column; no top organic layers) c5s0o (conventional land process scheme; physically-based soil property values; 5-layer 4m soil column; no top organic layers) p5s0 (partial refinement (no unfrozen water); physically-based soil property values; 5-layer 4m soil column; no top organic layers) r6s1(refined permafrost dynamics; physically-based soil property values; 6-layer 14m soil column; top organic layers) rCs0 (refined permafrost dynamics; physically-based soil property values; 12-layer 100m soil column; no top organic layers) rCs1y (refined permafrost dynamics; physically-based soil property values; 12-layer 100m soil column; top organic layers; different hydraulic parameters) rCs1 (refined permafrost dynamics; physically-based soil property values; 12-layer 100m soil column; top organic layers) The work was partially supported by NSF Grant number ARC-0327664, 0652838. The MIROC GCM was developed by CCSR (Univ. Tokyo), NIES and FRCGC, Japan. Simulations were done at the Arctic Research Supercomputing Center (ARSC).
