The National Center for Atmospheric Research (NCAR) and University Corporation for Atmospheric Research (UCAR) offer the Research Applications Laboratory (RAL), which aims to "conduct directed research that contributes to fundamental understanding of the atmosphere and related physical, biological, and social systems; to support, enhance, and extend the capabilities of the scientific community; and to develop and transfer knowledge and technology for the betterment of life on Earth." On their website, RAL offers a number of publications relating to the lab's research. Visitors can browse these publications, organized by date, in the Publications section of the Who We Are tab; some of these articles are freely available, while others require subscriptions to publishing institutions. This section includes a link to the Open Sky Lab, which features archival material relating to the NCAR. Alternatively, visitors can also browse publications by topic via the What We Do Section, which features publications, articles, and information about ongoing research projects organized into six categories: Aviation Applications, Climate Science & Applications, Hydrometeorology Applications, Joint Numerical Testbed, National Security Applications, and Weather Systems and Assessment.
