emerging issues and the research needed to develop the capacity to deal with them, and transfer important research results into operations. We need to start by recognizing that as the world and the United States’ challenges have changed, the scientific research priorities and operational priorities need to change as well. As such, this report and its recommendations are relevant to all parties in the weather enterprise: agency decision makers, policy makers, research scientists, private-sector applications specialists, teachers, public and private user groups and organizations, and the general public. In particular, this report is intended to inform NASA, NOAA, and NSF program managers and policy makers of the many priorities that need to be addressed in guiding the future of U.S. weather research and operations.
