资源简介：
The 48-month Standardized Precipitation-Evapotranspiration Index (SPEI-48) is an indicator used to monitor meteorological drought based on precipitation and reference evapotransipration. Anomalies over 48-month accumulation periods. SPEI-48 serves as a proxy indicator for long-term impacts, such as reduced reservoir and groundwater recharge. The input data for calculating the SPEI-48 is ERA5 precipitation and temperature reanalysis.
