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.
