The drought index (DI) is computed using SMOS derived root zone soil moisture (RZSM) monthly fields. The concept is to consider 13 years of SMOS data (2010-2022). The RZSM monthly mean and max over the period is iused to compute a soil water deficit to remove seasonal variability. from teh soil water deficit a soil moisture drought index is computed .The range of values for SMDI lies between -4 to +4, with -4 representing extreme dry conditions and +4 representing extreme wet conditions.

This product is established from one of the SMOS product: the optical thickness. The optical thickness or VOD is obtained directly from SMOS data by use of the multi-angular capability. For low vegetation (grass, crops,...) it is linked mainly to the water content while for forested areas it is more linked to the above ground biomass (AGB). The product is a yearly aggregation of AGB derived using different references (ESA BIOMASS CCI, Avitabile AGB estimates etc...) and is available for SMOS life time (2010 - now)
