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.. Molecular nitrogen (N2) . is a very common chemical compound in which two nitrogen atoms are tightly bound together. . The . strong triple-bond between the atoms in molecular nitrogen makes this compound difficult to break apart, and thus nearly .
