资源简介：
The 12-month Standardized Precipitation Index (SPI-12) is an indicator used to monitor meteorological drought based on precipitation anomalies over 12-month accumulation periods. SPI-12 serves as a proxy for medium-term impacts, such as reduced stream flow and reservoir storage, and for long-term impacts, such as reduced reservoir and groundwater recharge. The input data for calculating the SPI-12 is CPC (NOAA (USA National Oceanic and Atmospheric Administration) Climate Prediction Center) global precipitation.
