The standardized precipitation indexes (SPI, including SPI-1, SPI-3, SPI-6, and SPI-12) at multi-temporal scales from 1998 to 2017 in Beijing-Tianjin-Hebei region were calculated based on the monitored precipitation data of meteorological stations and Tropical Rainfall Measuring Mission (TRMM) V7 3B43 products. The results showed that the monthly and annual precipitation data of TRMM 3B43 products were consistent with that of the meteorological stations in Beijing-Tianjin-Hebei region in terms of time variation and space distribution. The SPI calculated by these two data sources agreed quite well at different time scales. In terms of spatial distribution, the SPI based on monthly TRMM 3B43 data showed a consistent variability compared with the actual monitored data of the 25 stations. The values of correlation coefficients were more than 0.7 and probability of detection (POD) values were more than 0.6. More than 80% of the false alarm ratio (FAR) values were less than 0.3, and more than 70% of the stations had frequency bias index (FBI) values ranging from 0.9 to 1.1. Moreover, the mean drought area percentage calculated by these two data sources matched well, and the Pearson correlation coefficient (CC) values were 0.93, 0.95, 0.96, and 0.96 at the different time-scales (SPI-1, SPI-3, SPI-6, and SPI-12), respectively.
