G-WADI GeoServer, a groundbreaking technology for real-time precipitation data

A meeting was held April 2014 at the Center for Hydrometeorology and Remote Sensing (CHRS) at the University of California to review the benefits of the Global Network on Water and Development Information in Arid Lands (G-WADI) GeoServer.


The G-WADI GeoServer provides satellite estimates of precipitation rates around the world in order to support flood forecasting as well as drought monitoring. At the meeting, case studies presented by countries from Africa, Asia, Europe, the Middle East, and LAC demonstrated its effectiveness in providing real-time data for disaster preparation.  The technology has also been used for various studies, including calibration studies in Thailand (2011) and extreme flood event monitoring in China (2012). Chile, after beginning using the GeoServer, evaluated its data as providing the best available real-time rainfall estimate. The purpose of the G-WADI GeoServer is to provide access to high resolution, near real-time global precipitation estimates to the water resources management community, particularly in developing countries where adequate hydrometeorological observations are scarce. The GeoServer is an interactive web interface (link hydis.eng.uci.edu/gwadi/) which shows precipitation rates around the world from satellite data. Using the MapServer technology, the interface allows users to zoom in on major storm events.  The server also offers a suite of related GIS data such as aridity, land cover, digital elevation, streams, and watersheds. To provide LAC countries with the best data for flood and drought preparation, UNESCO offers the G-WADI GeoServer to governments, universities, and individuals. It can be downloaded here. For users less familiar with this technology, the tutorial can provide more information. As scientists continue to build its capacity, agencies such as NASA, UNESCO-IHP, ICIWaRM and others commit to supporting and facilitating its use for member states.
