Impact of vegetation changes on climate during the Last Interglacial

This dataset contains the climatology of ocean, atmospheric, and sea-ice outputs of the lig127k-GlbVeg experiment integrated using the ACCESS-ESM1.5, averaged from 200 model years of simulation. The lig127k-GlbVeg experiment is similar to the PMIP4 lig127k. Both are equilibrium experiments of the Last Interglacial (127,000 years ago) and follow the CMIP6-PMIP4 protocol. While lig127k has a global vegetation cover corresponding to the pre-industrial climate conditions, lig127k-GlbVeg uses vegetation maps generated by a vegetation model, LPJ-GUESS, based on the ACCESS-ESM1.5 Last Interglacial conditions.

## Description of the data and file structure

The results presented in this study are based on simulations with the Australian Community Climate and Earth System Simulator (ACCESS-ESM1.5, Ziehn et al., 2020), which is a fully coupled atmosphere-land-ocean-sea-ice-carbon-cycle model.

The model was first integrated under Last Interglacial (LIG, 127,000 years ago, lig127k) boundary conditions following the PMIP4 protocol (Otto-Bliesner et al., 2017). The model is forced by appropriate orbital parameters and atmospheric greenhouse gas concentrations (Yeung et al., 2021). In this experiment, the vegetation cover is fixed to its pre-industrial distribution

The results of this experiment are then used to force the vegetation model, LPJ-GUESS, to obtain a vegetation distribution consistent with the simulated LIG climate.

An additional exper...,

本数据集包含基于澳大利亚社区气候与地球系统模式（ACCESS-ESM1.5）积分得到的lig127k-GlbVeg试验的海洋、大气及海冰输出气候态，该气候态取自200个模式模拟年的平均结果。lig127k-GlbVeg试验与古气候模式比较计划第四期（PMIP4）的lig127k试验相似，二者均为末次间冰期（距今12.7万年）的平衡试验，且均遵循耦合模式比较计划第六期-古气候模式比较计划第四期（CMIP6-PMIP4）试验规范。其中lig127k试验的植被覆盖设定为工业革命前气候条件下的分布，而lig127k-GlbVeg试验则采用基于ACCESS-ESM1.5模拟的末次间冰期气候条件，由植被模型LPJ-GUESS生成的植被分布图作为植被强迫场。

## 数据与文件结构说明

本研究采用的模拟结果基于澳大利亚社区气候与地球系统模式（ACCESS-ESM1.5，Ziehn等，2020），该模式为全耦合大气-陆地-海洋-海冰-碳循环模式。

该模式首先按照古气候模式比较计划第四期（PMIP4）试验框架（Otto-Bliesner等，2017），在末次间冰期（LIG，距今12.7万年，即lig127k）边界条件下进行积分，试验强迫场采用适配的轨道参数与大气温室气体浓度（Yeung等，2021）。本试验中，植被覆盖被固定为工业革命前的分布状态。

随后，该试验的模拟结果被用作植被模型LPJ-GUESS的强迫场，以获取与模拟得到的末次间冰期气候相匹配的植被分布。
