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 displays maps of meteorological drought risk using the standardized precipitation index SPI. It allows the user to choose between maps of either the predicted drought severity for a user-specified likelihood or the risk of a certain magnitude of drought level happening.
    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.
