The first high spatial resolution multi-scale daily SPI and SPEI raster dataset over China from 1979 to 2018

This is a collection containing all our improved daily SPI/SPEI raster datasets and the traditional monthly SPI/SPEI fitting by various probability distributions. The A in the filename "A_B_C_D_E-F.nc" (e.g. Daily_SPEI_GEV_30D_1979-2018.nc) represents the dataset temporal resolution. B is the name of the drought index. C is the name of the probability distribution function. D is the timescale. E-F is the start and end time of the dataset.If you use our data in your research, please cite our data and papers. If possible, please let us know in the early stages of your research to ensure that your work does not significantly overlap with the products we are currently working on. Additionally, if our dataset is critical to your research, co-authors may be appropriate. You must inform us of your analysis and publication plans well in advance of submission of a paper, give us an opportunity to read and intellectually contribute to the manuscript, and, if appropriate, offer co-authorship.Contact: Prof. Qianfeng Wang ([e-mail])
