Mapping meteorological drought hazard

Statement

Data requirements to use: Monthly precipitation;

Data used: N/A;

Data format: N/A;

Data access: N/A;

Concise description:

CZI is similar to SPI because precipitation is used to determine wet and dry periods, assuming that the precipitation obeys a Pearson type III distribution. It uses monthly time steps from 1 to 72 months, giving it the ability to identify droughts of various durations.
