User Highlights¶
RAPID is used by leading research institutions and scientific organizations worldwide.
A 35-year historical simulation produced with RAPID is used to provide a first guess for discharge estimates by the international Surface Water and Ocean Topography (SWOT) mission that is jointly developed by NASA and CNES. Read more in the simulation paper and the SWOT discharge paper.
A 40-year historical simulation and its associated 15-day ensemble forecast for every river in the world produced with RAPID support the ECMWF GEOGLOWS Streamflow system. Read more in the research paper or on the GEOGLOWS ECMWF Streamflow website.
RAPID is used for global hydrologic intelligence. Read more in the research paper or in the USACE news story.
