EDO Combined Drought Indicator (CDI) (version 3.0.2)

Collection: DROUGHT : Drought Observatories datasets 

Description

Combined Drought Indicator based on SPI, soil moisture and fAPAR, to identify areas with potential to suffer agricultural drought, areas where the vegetation is already affected by drought conditions, and areas in recovery process to normal conditions after a drought episode. The method is based in 6 impact levels. These levels are: "Watch" when a relevant precipitation shortage is observed, "Warning" when this precipitation shortage comes with a soil moisture anomaly, "Alert" when these two conditions are accompanied with an anomaly in the vegetation condition, "Temporary Soil Moisture recovery" when after a drought episode, soil moisture conditions went below the drought threshold but did not improve enough to consider the episode closed; "Temporary Vegetation recovery" when after a drought episode, vegetation conditions went below the drought threshold but did not improve enough to consider the episode closed; "Recovery" when meteorological, soil moisture, and vegetation normal conditions are recovered.
