About This Statistic
The SPEI fulfills the requirements of a drought index since its multi-scalar character enables it to be used by different scientific disciplines to detect, monitor, and analyze droughts. Like the sc-PDSI and the SPI, the SPEI can measure drought severity according to its intensity and duration, and can identify the onset and end of drought episodes. The SPEI allows comparison of drought severity through time and space, since it can be calculated over a wide range of climates, as can the SPI.
MapTheory retains one fixed reference year and unit. Only finite values mapped to ISO 3166-1 numeric codes are included; aggregates, missing values and non-ISO geographies are excluded. No value is estimated, imputed or carried across years.
