World Bank

Working in collaboration with the World Bank, IRI has developed a map tool that enables a user to examine the components of variability of historical precipitation and temperature data at various time scales (interannual, decadal, and linear trend) during the 20th century. The tool was developed to serve as a component of the World Bank Climate Change Data Portal.

    This tool allows a user to investigate the historical variability of precipitation and temperature at various time scales (interannual, decadal, and long-term linear trend) over the 20th century near a user-selected location.
    This tool displays maps of probabilitic SPI and allows the user to choose between a map of the predicted drought severity for a user-specified level of likelihood or a map of probabilities of a certain drought level happening.
