The GRACE codes for the study on "Increased wheat price spikes and larger economic inequality with 2C global warming"

1. The document (CodeGRACE.zip, the same as Version 1) includes all the programming codes of the version of GRACE used by Zhang et al. (2022). "Increased wheat price spikes and larger economic inequality with 2C global warming." One Earth 5(8): 907-916. DOI: 10.1016/j.oneear.2022.07.004. 2. In this version, the main region-level data of results simulated by GRACE are added, i.e., the zip file "ResultsData.zip". 3. No other updates in Version 2.1. 本数据集配套文件（CodeGRACE.zip，与版本1一致）包含了Zhang等人（2022年）所使用的GRACE版本的全部程序代码。对应论文为《2℃全球变暖背景下小麦价格暴涨与经济不平等扩大》，发表于《One Earth》2022年第5卷第8期，页码907-916，DOI：10.1016/j.oneear.2022.07.004。 2. 本版本新增了GRACE模拟所得结果的主要区域级数据，即压缩文件ResultsData.zip。 3. 版本2无其他更新内容。
