A New Drought Index for Soil Moisture Monitoring Based on MPDI-NDVI Trapezoid Space Using MODIS Data
The temperature vegetation dryness index (TVDI) has been commonly implemented to estimate regional soil moisture in arid and semi-arid regions.However, the parameterization of the dry edge in the TVDI model is performed with a constraint to define the maximum water stress conditions.Mismatch of the spatial scale between visible and thermal bands re
