Description
The Water Deficit product is derived from processing MOD16A2 MODIS/Terra Net Evapotranspiration 8-Day L4 Global 500 m version 6 image collection to generate a time series of the Water Deficit.
Climatic Water Deficit is the difference between the potential and the actual evapotranspiration (PET-AET).
