Integrated Drought Indices
Integrated Drought Index Concurance Measure
Topo Map
3 month Integrated Precipitation Index
Notes about this product:
  • The integrated drought index is the mean of the ensemble mean soil moisture percentiles and the SRI3 averaged over all models.
  • The concurrence measure is the percentage of indices in the same category as the integrated drought index.
