    [Quick Report] Monitoring extreme heavy rainfall in UAE by Global Satellite Mapping of Precipitation (GSMaP)
    The United Arab Emirates (UAE) experienced record rainfall on April 16, 2024. In the country where the majority of the land is desert, the precipitation levels were reported to be more than twice the annual average, resulting in flood damage in many regions.
    JAXA is monitoring the precipitation from space through the Global Satellite Mapping of Precipitation (GSMaP). The present report is an analysis of precipitation in the UAE.
