Operational Microwave-Adjusted Hydro-Estimator to support Flash Flood Assessments Worldwide
Abstract
To support the deployment of an operational system for flash flood assessment worldwide, precipitation forcing from satellite sensors with high spatio-temporal resolution and low latency is necessary. In this presentation we discuss the merging of the infrared-based NESDIS operational global Hydro-Estimator with the microwave/infrared-based CMORPH precipitation estimates on hourly scales and in real time, to feed the Flash Flood Guidance System with global coverage. The latter system, whose implementation is facilitated by a partnership among the World Meteorological Organization, USAID/Bureau for Humanitarian Assistance, NOAA, and Hydrologic Research Center enables forecasters to make assessments pertaining to the occurrence of flash floods in small basins (of area several tens of square kilometers) that tile their countrys domain. At present the system is serving more than 60 countries worldwide. The presentation will further discuss the operational climatological and dynamic bias adjustment of the satellite-based precipitation estimates with precipitation from ground-based gauges, and will provide error measures in diverse regions worldwide.
