Abstract

This dataset includes an estimate of Standardized Precipitation Index for 1, 3, 6, 9, 12 months time interval. It is based on two sources: 1) A global daily gridded precipitation dataset obtained from the Centre for Hydrometeorology & Remote Sensing of Univeristy of California, Irvine, USA. 2) A GIS modeling of global Standardized Precipitation Index based on Mckee et al. (1993) methodology. Unit is SPI index. It was modeled using global data. Credit: International Water Management Institute (IWMI), Sri Lanka
