UCAR carries out its mission through two organizations: The National Center for Atmospheric Research (NCAR) and the UCAR Office of Programs (UOP).
The UCAR Office of Programs supplies real-time weather data to colleges and universities for use in the classroom, trains weather forecasters in the latest research results and technologies, and helps organize international experiments in remote areas of the world, among other services.
In FY 2001, UCAR expenditures were $148 million. The principal sponsor is the National Science Foundation (NSF); funds also come from the National Oceanic and Atmospheric Administration (NOAA), National Aeronautics and Space Administration (NASA), the Department of Defense (DOD), Federal Aviation Administration (FAA), Department of Energy (DOE), Environmental Protection Agency (EPA), and other agencies and organizations.
UCAR also operates the multinational GLOBE Program, a hands-on, school-based education and science program that seeks to teach young students using real experiments, equipment and collaboration with students in a global network of scientists and educators.
