Drought events in the GHA region

This dataset includes an estimate of regional drought annual repartition based on Standardized Precipitation Index. It is based on two sources: 1) A global monthly gridded precipitation dataset obtained from the Climatic Research Unit (University of East Anglia). 2) A GIS modeling of global Standardized Precipitation Index based on Brad Lyon (IRI, Columbia University) methodology. Drought events are defined as area where monthly precipitation are lower than 50% of the median value calculated for the period 1961-1990 during at least three consecutive months
