A SPEI dataset in China-Pakistan Economic Corridor from 1961 to 2015

Drought index data set is the basis of drought research. Drought disasters occur frequently in the China Pakistan Economic Corridor. Making the drought index data set is of great scientific significance for drought monitoring and risk assessment. Based on daily precipitation and temperature gridded data of the China-Pakistan Economic Corridor from 1961 to 2015 and calculated standardized precipitation evapotranspiration index (SPEI) for different time scales (1- 24 months). The verification shows that this dataset has high accuracy and can better reflect the real temporal and spatial distribution characteristics of drought in China-Pakistan Economic Corridor area. The dataset can provide substantial support for climate change research and assessment of drought disaster risk over the China-Pakistan Economic Corridor.

干旱指数数据集是干旱研究的基石。在中国-巴基斯坦经济走廊，干旱灾害频发。构建干旱指数数据集对于干旱监测与风险评估具有重大的科学价值。本数据集基于1961年至2015年间中国-巴基斯坦经济走廊的每日降水和温度网格化数据，并计算了不同时间尺度（1-24个月）的标准化降水蒸散指数（SPEI）。验证结果表明，该数据集具有较高的准确性，并能更有效地反映中国-巴基斯坦经济走廊区域干旱的时空分布特征。该数据集可为气候变化研究及中国-巴基斯坦经济走廊干旱灾害风险评估提供重要支撑。
