This dataset mainly includes the spatial distribution of global SPEI in 1218 in 2018, the global drought intensity in 2018, and the anomalies of precipitation, land surface temperature, 0-10 cm soil moisture and the past 10 years (2009-2018); The flat index method, the maximum value synthesis method and the trend analysis method calculate the global drought intensity and the main meteorological factor anomaly data for 2018. The data time scale is 2018-01-01 to 2018-12-31, and the spatial resolution is 0.5 degree. The data can provide a scientific reference for the analysis of global drought distribution and drought assessment in 2018.

File naming and required software

File naming: SPEI data is stored in tif format for 12 months in 2018. The file name is “yyyymm_SPEI_2018.tif”, where yyyy represents the year and mm represents the month; 2018 global drought intensity data is stored in tif format, and the file name is “global_droughti_intensity. Tif"; temperature anomaly is stored in tif format, the file name is "temperature_anomaly10yr.tif"; the soil moisture anomaly is stored in tif format, the file name is "SoilMoi0_10cm_anomaly10yr.tif"; the precipitation anomaly is stored as tif, the file name is "precipitaiton_anomaly10yr" .tif"
Data reading method: open directly with envi and arcgis
