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.
