Combined Drought Index (CDI)

Combined Drought Index (CDI). It helps to identify agricultural drought over LMR, based on a combination of three indicators. Anomalies of precipitation (SPI-3), soil moisture and the fraction of Absorbed Photosynthetically Active Radiation (fAPAR) are used as the basic indicators to design a prototype of the so-called Combined Drought Indicator (CDI), characterizing the different stages of the agricultural drought cause effect relationship. The CDI depicts the spatial extent of a drought situation and gives an overview of the possible consequences for agriculture, classifying the affected areas with a watch when there is a precipitation deficit, a warning when this precipitation deficit leads to a soil moisture deficit, and an alert when the two previous conditions result in a reduction of the vegetation production. This product is generated from RHEAS modeling framework using CHIRPS rainfall, NCEP temperature and wind, SMAP/SMOS soil moisture, NMME seasonal forecast products in 0.25-degree resolution to cover LMR.
