China 0.1° Extreme Climate Index Dataset from 1979 to 2018

The CECID (China Extreme Climate Index Dataset), a 0.1° extreme climate index dataset for China from 1979-2018, was calculated based on the China Surface Meteorological Element Driven Dataset (CMFD) and the China Near Surface Air Temperature Dataset (CDAT) using the R language program package climdex.pcic , the dataset covers 27 extreme climate indices. The correlation coefficients of most of the indicators (e.g., FD, TR, R10mm, PRCPTOT) are above 0.7 compared with the public extreme climate index datasets. The CECID can be used for studying the characteristics of extreme climate events in China and their impacts on ecosystems. It holds practical value and significance in disaster prevention, climate change assessment, and related fields.

CECID（中国极端气候指数数据集，China Extreme Climate Index Dataset）是一套1979-2018年中国区域0.1°分辨率极端气候指数数据集，基于中国地表气象要素驱动数据集（CMFD）与中国近地面气温数据集（CDAT），通过R语言程序包climdex.pcic计算生成，该数据集共涵盖27项极端气候指数。与公开的极端气候指数数据集相比，该数据集多数指标（如FD、TR、R10mm、PRCPTOT）的相关系数均高于0.7。CECID可用于研究中国极端气候事件的特征及其对生态系统的影响，在防灾减灾、气候变化评估及相关研究领域具有实际应用价值与意义。
