GDO Standardized Precipitation-Evapotranspiration Index ERA5, 6-month accumulation period (SPEI-6) (version 1.0.0)

Collection: DROUGHT : Drought Observatories datasets 

Description

The 6-month Standardized Precipitation-Evapotranspiration Index (SPEI-6) is an indicator used to monitor meteorological drought based on precipitation and reference evapotransipration. Anomalies over 6-month accumulation periods. SPEI-6 serves as a proxy for medium-term impacts, such as reduced stream flow and reservoir storage. The input data for calculating the SPEI-6 is ERA5 precipitation and temperature reanalysis.
