Concise description:

Uses daily precipitation data to develop and compute several parameters: effective precipitation (EP), daily mean EP, deviation of EP (DEP) and the standardized value of DEP. These parameters can identify the onset and end of water deficit periods. Using the input parameters, EDI calculations can be performed for any location in the world in which the results are standardized for comparison, giving a clear definition of the onset, ending and duration of drought. At the time of EDI’s development, most drought indices were being calculated using monthly data, so the switch to daily data was unique and important to the utility of the index.
