Data for manuscript "Mid-Pliocene glaciation preceded by a 0.5-million-year North African humid period"

This repository contains model data accompanying the manuscript: Udara Amarathunga, Eelco J. Rohling, Katharine M. Grant, Alexander Francke, James Latimer, Robert M. Klaebe, David Heslop, Andrew P. Roberts and David K. Hutchinson, 2024: Mid-Pliocene glaciation preceded by a 0.5-million-year North African humid period, Nature Geoscience, 10.1038/s41561-024-01472-8 There are three main folders: inputs.tgz: containing input files for each simulation outputs.tgz: containing model outputs (as shown in the manuscript) restarts.tgz: containing restart file bundles for the end of each simulation. There are three experiments, as described in the manuscript. These are labelled: early_plio: Early Pliocene (3.312 - 5.3 Myr) plio_glac: M2 glacial (3.264 - 3.312 Myr) plio_m2: Mid-Pliocene glacials (3.0 - 3.264 Myr) The output data are either monthly or annual frequency, as indicated by the filename. 3D ocean outputs are in annual frequency only, while some surface 2D ocean fields are provided at monthly resolution. 3D atmosphere outputs are in monthly frequency. All data are provided in self-describing netcdf format. The model uses GFDL CM2.1, reconfigured with MOM5.1, which is available to download from https://github.com/mom-ocean/MOM5.本仓库包含与下述学术论文配套的模型数据集： Udara Amarathunga、Eelco J. Rohling、Katharine M. Grant、Alexander Francke、James Latimer、Robert M. Klaebe、David Heslop、Andrew P. Roberts 与 David K. Hutchinson，2024年：《早于中上新世冰川作用的0.5百万年北非湿润期》，《自然·地球科学》（Nature Geoscience），DOI: 10.1038/s41561-024-01472-8 本仓库包含三个核心文件夹： - inputs.tgz：存储所有模拟实验的输入文件 - outputs.tgz：存储论文中展示的模型输出结果 - restarts.tgz：存储各模拟实验结束时的重启文件包 本数据集包含论文中描述的三组实验，命名如下： early_plio：上新世早期（5.3 百万年 — 3.312 百万年） plio_glac：M2 冰期（3.312 百万年 — 3.264 百万年） plio_m2：中上新世冰期（3.264 百万年 — 3.0 百万年） 输出数据的时间分辨率分为逐月与逐年两类，可通过文件名识别。其中三维海洋输出仅提供逐年分辨率数据，部分表层二维海洋场则以逐月分辨率提供；三维大气输出均采用逐月分辨率。 所有数据均采用自描述性NetCDF（网络通用数据格式）存储。 本研究使用的模式为经重新配置的GFDL CM2.1耦合模式，其海洋分量采用MOM5.1（模块化海洋模式5.1），该模式可从 https://github.com/mom-ocean/MOM5 下载获取。
