Committee on Partnerships in Weather and Climate Services, Committee on Geophysical and Environmental Data, Board on Earth Sciences and Resources, Board on Atmospheric Sciences and Climate, Computer Science and Telecommunications Board, Division on Earth and Life Studies, National Research CouncilDecades of evolving U.S. policy have led to three sectors providing weather services—NOAA (primarily the National Weather Service [NWS]), academic institutions, and private companies. This three-sector system has produced a scope and diversity of weather services in the United States second to none. However, rapid scientific and technological change is changing the capabilities of the sectors and creating occasional friction.Fair Weather: Effective Partnerships in Weather and Climate Servicesexamines the roles of the three sectors in providing weather and climate services, the barriers to interaction among the sectors, and the impact of scientific and technological advances on the weather enterprise. Readers from all three sectors will be interested in the analysis and recommendations provided inFair Weather.
