资源简介：
The 1-month Standardized Precipitation Index (SPI-1) is an indicator used to monitor meteorological drought based on precipitation anomalies over 1-month accumulation periods. SPI-1 serves as a proxy indicator for immediate impacts of droughts such as reduced soil moisture, snowpack, and flow in smaller creeks. The input data for calculating the SPI-1 is CHIRPS (Climate Hazards Group InfraRed Precipitation with Station data) rainfall estimates from rain gauge and satellite observations, version 3.0, baseline 1991-2020.
