The California Water Resources RESAC objectives were to utilize NASA data to provide state-of-the-art real-time and forecast information (observation and simulation) on hydroclimate, water quantity and quality, and runoff related hazards to water resources managers (e.g., NWS, CA Dept. of Water Resources, USBR), the insurance industry, emergency response agencies, policy decision-makers, and the general public. In addition, the RESAC acts as an umbrella organization fostering growing collaborations and partnerships. It was built on the foundation established through the U.S. Global Change Research Program and the National and California Assessments. It is designed to support the ongoing regional and national assessment process by improving our understanding of specific regional features of the climate system and its impacts, and facilitating the dissemination of these results through data, publications, and outreach.The California Water Resources RESAC produces three types of regional climate products that are enhanced by incorporation of NASA satellite data: (1) short-term (2-3 day) weather and streamflow forecasts, (2) seasonal hydroclimate, and (3) long-term climate change scenarios and hydrologic impacts. Our team has built an excellent record in providing quantitative precipitation and streamflow forecasts to the water resources and weather prediction communities. We have been working with scientists from various University of California institutions and government agencies to improve weather and streamflow predictions and studies of regional hydroclimate, and its impacts on water resources, the environment, and the economy.
