Antarctic Ice Sheet simulations for role of freshwater in future warming scenarios

Abstract: The dataset consists of two tar files for two distinct sets of simulations. Each tar file contains a number of Netcdf files with model output for one simulation each, and also contains a DIF file (Directory Interchange Format, in xml form) with information on that part of the dataset. Set 1: There are 4 Netcdf files with output from the PSU 3D Antarctic ice sheet model including ice melange, showing role of melange in potentially providing buttressing and possibly slowing down ice retreat in strong climate warming scenarios. Set two: There are 2 Netcdf files with output from the PSU 3D Antarctic ice sheet model, for two future warming scenarios RCP4.5 and RCP8.5, contributing to oceanic meltwater discharge fields for future climate and ocean model simulations performed at Univ. Massachusetts by other PIs on the NSF project. More details on file names and model fields is provided in "Data Content" section.摘要：本数据集包含两个tar文件，分别对应两组独立的模拟实验。每个tar文件内含若干NetCDF（网络通用数据格式，Network Common Data Form）文件，每个文件存储单组模拟的模型输出结果；同时还附带一个DIF文件（目录交换格式，Directory Interchange Format，XML格式），用于记录该子数据集的相关信息。 数据集第一组： 包含4个NetCDF文件，存储PSU三维南极冰盖模型的模拟输出结果，涵盖冰杂岩相关数据，用以揭示冰杂岩在强气候变暖情景下，对冰盖可能起到的支撑作用，以及延缓冰盖退缩的潜在机制。 数据集第二组： 包含2个NetCDF文件，存储PSU三维南极冰盖模型的模拟输出结果，对应RCP4.5与RCP8.5两种未来增温情景。该数据集可为马萨诸塞大学（University of Massachusetts）其他项目首席研究员依托美国国家科学基金会（National Science Foundation, NSF）项目开展的未来气候与海洋模型模拟，提供海洋融水径流场数据。 更多关于文件名与模型字段的细节，请参见"数据内容"章节。
