South American frozen ground distribution for LGM, mid-Holocene and pre-Industrial periods

Model ensemble South American frozen ground distribution classified from the CMIP5/PMIP3 simulation outputs and downscaled with help of the digital elevation model ETOPO1 for LGM, mid-Holocene and pre-Industrial periods.本数据集为模式集合（Model ensemble）南美洲冻土分布数据，基于耦合模式比较计划第五阶段（Coupled Model Intercomparison Project Phase 5，CMIP5）与古气候模式比较计划第三阶段（Paleoclimate Modelling Intercomparison Project Phase 3，PMIP3）的模拟结果分类得到，并借助数字高程模型（Digital Elevation Model）ETOPO1针对末次盛冰期（Last Glacial Maximum，LGM）、中全新世及前工业时期开展了降尺度处理。
