Index: SPEI, The Standardised Precipitation-Evapotranspiration Index The SPEI 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
SPEI Global Drought Monitor - CSIC The SPEI 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
Data base: SPEI, The Standardised Precipitation . . . - CSIC Information 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
Information SPEI, The Standardised Precipitation-Evapotranspiration Index Therefore a new drought index (the Standardized Precipitation Evapotranspiration Index; SPEI) has been formulated based on precipitation and PET The SPEI combines the sensitivity of PDSI to changes in evaporation demand (caused by temperature fluctuations and trends) with the simplicity of calculation and the multi-temporal nature of the SPI
