It is NCAR's mission to plan, organize, and conduct atmospheric and related research programs in collaboration with the universities and other institutions, to provide state-of-the-art research tools and facilities to the atmospheric sciences community, to support and enhance university atmospheric science education, and to facilitate the transfer of technology to both the public and private sectors..
