The Standardised Precipitation-Evapotranspiration Index is a multiscalar drought index based on climatic data. It can be used for determining the onset, duration and magnitude of drought conditions with respect to normal conditions in a variety of natural and managed systems such as crops, ecosystems, rivers, water resources, etc.
|
| The Global SPEI database, SPEIbase, offers long-time, robust information about drought conditions at the global scale, with a 0.5 degrees spatial resolution and a monthly time resolution. It has a multi-scale character, providing SPEI time-scales between 1 and 48 months. It is based on monthly precipitation and potential evapotranspiration data from the Climatic Research Unit of the University of East Anglia, starting in January 1901, and it is updated as soon as new data becomes available.
