Abstract & Keywords
Abstract: Xinjiang is located in the Eurasian hinterland in northwestern China. With complex terrain and fragile ecological environment, Xinjiang is particularly sensitive to global warming. Indeed, drought in Xinjiang has attracted extensive attention under global warming. Based on daily temperature and precipitation observed at 55 meteorological stations over Xinjiang during 1961 – 2015, this study calculated a series of drought indices based on the Standardized Precipitation Evapotranspiration Index (SPEI). The SPEI was calculated for each station with selected time scales of 1, 3, 6, 12, 24 and 48 months. This dataset is useful for research on the trends and spatial-temporal characteristics of drought events over Xinjiang. When used together with regional statistics, it helps reveal the impacts of drought on agricultural production and eco-hydrological environment.

Dataset compositionThis dataset consists of 6 .xlsx files which record drought indices at different timescales, including SPEI 1mo, SPEI 3mo, SPEI 6mo, SPEI 12mo, SPEI 24mo and SPEI 48mo timescale drought indices. Files of this dataset are named after their index names in English. Each file consists of information on year, month, SPEI index results, and WMO site numbers. Each file has a slightly different data volume depending on the number of sites and the different timescales used. The amount of uncompressed data is about 2.38 MB.
