1-month Standardized Precipitation Index for agriculture drought (September 2009)

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
