Cautions
The maps of soil moisture anomalies can be used as a “proxy” for the presence of potential drought conditions. Of course, the presence of actual water stress conditions will also depend on the specific plants’ resistance and capacity for water extraction from the soil matrix. The Triple Collection method (combination of three base products) provides accurate estimates of the weighting factors only under very strict hypotheses.
