Description

The Combined Drought Indicator (CDI) is an indicator for drought early warning, specifically designed to monitor agricultural drought. Through the combination of spatial patterns of precipitation, soil moisture and greenness vegetation anomalies, the CDI identifies areas at risk of agricultural drought, areas where the vegetation has already been affected by drought and areas in the process of recovery to normal conditions. Accordingly, the CDI classification scheme defines three primary drought classes (Watch, Warning and Alert) and three recovery classes (Temporary Soil Moisture Recovery, Temporary Vegetation Recovery and Full Recovery).
