AB: During August, 2007, torrential rains caused 50 deaths in Yemen. During the same month, severe storms caused 320 losses of lives and the displacement of more than 400,000 people. These disasters highlight the critical need for globally coordinated efforts to improve the availability of and timeliness of precipitation information in many areas in the world. Satellite observation and estimates of precipitation are now mature enough to provide real-time global precipitation information. In collaboration with UNESCO' International Hydrologic Programm (IHP) and the NOAA's National Satellite and Information Service (NESDIS), the Hydrologic Data and Information System (HyDIS) team at the Center for Hydrometeorology and Remote Sensing (CHRS), of the University of California, Irvine is building a the G-WADI GeoServer to provide global realtime high-resolution precipitation estimates from satellite data as a key element of the US's contributions to UNESCO's Water And Development Information for Arid Lands – A global Network (G-WADI ) program. This presentation will highlight key features and services of the G-WADI Geo-Server such as its geospatial browsing capabilities, country and watershed report generation tools, and severe precipitation mapping options. It will also discuss current validation efforts aiming at assessing the reliability and quality of the underlying provisional high-resolution precipitation product in comparison with radar, gauges, and with quality controlled estimates with emphasis on some recent storms. Additional satellite precipitation data access tools will be presented and the architecture of the system, which is based on the USGS implementation of the University of Minnesota MapServer, will be briefly discussed to highlight the system's portability and compliance with UNESCO's requirements.
