GDO Standardized Precipitation Index CHIRPS, 9-month accumulation period (SPI-9) (version 1.0.0)

Collection: DROUGHT : Drought Observatories datasets 

Description

The 9-month Standardized Precipitation Index (SPI-9) is an indicator used to monitor meteorological drought based on precipitation anomalies over 9-month accumulation periods. SPI-9 serves as a proxy indicator for medium-term impacts, such as reduced stream flow and reservoir storage. The input data for calculating the SPI-9 is CHIRPS (Climate Hazards Group InfraRed Precipitation with Station data) rainfall estimates from rain gauge and satellite observations.
