Global Water Sustainability Tools from Earth Observations for the Americas
Abstract
Recently, improvements in hydrometeorological models and "Big-Data" management and delivery from cloud computing have enabled using global models use in supporting decision-making in water resources at local levels. As part of an academic-governmental-private partnership of the Group on Earth Observations (GEO) Global Water Sustainability (GEOGloWS) initiative, we developed a set of web services that provides such a global hydrological model with the ability to provide a global daily, probabilistic 15-day forecast. Access to these forecasts are free and open with services that allow for customization at regional, national, and local scales. We added additional global tools using datasets from NASA's Global Land Data Assimilation System (GLDAS) and NOAA's Global Forecast System (GFS) within the Tethys Platform for web app development and deployment complement the streamflow forecasts and provide a complete toolkit for water resources decision-making from earth observations.
These GEOGloWS Hydro-met informatics apps are key tools for supporting decision making at both operational and medium- to long-term planning that help stakeholders prioritize investments for water resources management and increase resilience. These apps are being used to strengthen national and regional hydro-meteorological services in Central America for improving water resources management overall, including the existing regional framework to support addressing water transboundary challenges. This GEOGloWS demonstration project with the CRRH-SICA (Regional Committee of Hydraulic Resources), a technical body of the Central American Integration System (SICA), specializing in Meteorology, Climatology, Hydrology and Water and Hydraulic Resources of the Central American region. It's mandate is to develop processes that strengthen the capacities of the Meteorological and Hydrological Services and the institutions that use the region's water, in the management of information on weather, climate and water, as well as technical support to specialized bodies and the SICA secretariats.- Publication:
