Global irrigation reservoirs are at a higher risk of water shortages

The folder contains the 3-month moving-averaged 1-month Standardized Storage Index (SSI) time series from 1999-2018 for 1,203 reservoirs. Each file corresponds to an individual reservoir, and the filename is associated with the reservoir’s GRAND_ID from the Global Reservoir and Dam (GRanD) database. The master file provides summary information for all reservoirs, including reservoir ID, geographic location, mean drought propagation time (Zscore), mean recovery time (Zscore), overall severity score (Zscore), relative risk level, and linkage probability (%).
