Title: EDO Combined Drought Indicator (CDI) (version 1.4.0)


Combined Drought Indicator (CDI) based in 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 5 impact levels. This 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, "Partial recovery" when after a drought episode, the meteorological conditions are recovered to normal but not the vegetation conditions, "Full recovery" when meteorological and vegetation normal conditions are recovered. Currently, historical data are being reprocessed.
