The global 1km resolution TVDI dataset (2020), Temperature Vegetation Drought Index (TVDI) is a soil moisture inversion model based on normalized difference vegetation index (NDVI) and land surface temperature (LST), which can better monitor drought, especially monitor the relative drought degree of the whole region in a certain period of a specific year, and can be used to study the spatial change characteristics of drought degree. The TVDI data of 12 months in the world are included, and the size of each pixel is 0.0089 degrees (~1 km2). Data naming rule: tvdi20yymm.tif represents global TVDI data in mm month of 26yy year.
