Additional information and datasetsused in Freund et al. 2019, Higher frequency of Central Pacific El Niño events in recent decades relative to past centuries rdcu.be/bAxOG --------------------------------------------------------------------------- File format provided: netcdf (.nc) and text format (.txt) --------------------------------------------------------------------------- Central Pacific El Niño events abbreviated as CP events (El Niño Modoki, Dateline El Niño, Central Pacific El Niño) Eastern Pacific El Niño events abbreviated as EP events (Traditional El Niño, canonical El Niño, Eastern Pacific El Niño) All frequency information is given as number of events per 30 year period. All intensity information is given as intensity of individual El Niño events as the maximum SSTA in Niño 3 and Niño 4 region. All ratio information is given as the number of Central Pacific El Niño events vs. Eastern Pacific El Niño events per 30 year periods. All uncertainty information is estimate by obtaining 1000 realisation bootstrap approach. See more details in methods and Supplementary Information (https://static-content.springer.com/esm/art:10.1038/s41561-019-0353-3/MediaObjects/41561_2019_353_MOESM1_ESM.pdf) 1) Instrumental data saved by : "Instrumental_"2) Reconstructed data saved by: "Reconstructed_"3) Uncertainty around reconstructed data saved as:"ReconstructedUncertainty_" Find cite and find further information in: Freund, M.

**额外信息与数据集** 用于Freund等（2019）发表于《Nature Geoscience》的《近几十年来中太平洋厄尔尼诺事件发生频率较过去数百年更高》研究的相关内容 rdcu.be/bAxOG --------------------------------------------------------------------------- 提供的文件格式：netCDF（.nc）与纯文本（.txt）格式 --------------------------------------------------------------------------- **中太平洋厄尔尼诺事件**简称CP事件，涵盖厄尔尼诺模态（El Niño Modoki）、日界线厄尔尼诺（Dateline El Niño）与中太平洋厄尔尼诺三种类型。 **东太平洋厄尔尼诺事件**简称EP事件，涵盖传统厄尔尼诺（Traditional El Niño）、经典厄尔尼诺（canonical El Niño）与东太平洋厄尔尼诺三种类型。所有**频率**统计结果均以每30年周期内的事件数量表征。所有**强度**统计结果均以单次厄尔尼诺事件在Niño 3与Niño 4区域的最大海表温度异常（Sea Surface Temperature Anomaly, SSTA）值作为强度表征。所有**比率**统计结果均以每30年周期内中太平洋厄尔尼诺事件与东太平洋厄尔尼诺事件的数量比值表征。所有**不确定性**统计结果均通过1000次自助法（bootstrap）重采样实验估算得到，详细方法请参见原文方法部分与补充材料（https://static-content.springer.com/esm/art:10.1038/s41561-019-0353-3/MediaObjects/41561_2019_353_MOESM1_ESM.pdf）。 1) 仪器观测数据以"Instrumental_"为前缀保存； 2) 重建数据以"Reconstructed_"为前缀保存； 3) 重建数据的不确定性信息以"ReconstructedUncertainty_"为前缀保存。 **如需获取引用信息与更多研究细节，请参阅：**Freund, M.
