资源简介：
The 3-month Standardized Precipitation Index (SPI-3) is an indicator used to monitor meteorological drought based on precipitation anomalies over 3-month accumulation periods. SPI-3 serves as a proxy for medium-term impacts, such as reduced stream flow and reservoir storage. The input data for calculating the SPI-3 is CHIRPS (Climate Hazards Group InfraRed Precipitation with Station data) rainfall estimates from rain gauge and satellite observations, version 3.0, baseline 1991-2020.
