Description
The 24-month Standardized Precipitation Index (SPI-24) is an indicator used to monitor meteorological drought based on precipitation anomalies over 24-month accumulation periods. SPI-24 serves as a proxy indicator for long-term impacts, such as reduced reservoir and groundwater recharge. The input data for calculating the SPI-24 is CHIRPS (Climate Hazards Group InfraRed Precipitation with Station data) rainfall estimates from rain gauge and satellite observations.
