US CLIVAR Project Office

The US CLIVAR Project Office, funded by NASA, NOAA, NSF, and DOE, and operated through the University Corporation for Atmospheric Research (UCAR) Joint Office of Science Support (JOSS), provides the critical infrastructure to enable the planning, implementation, and communication of scientific research activities of the US CLIVAR Program. The Office is comprised principally of three individuals – a Director and Program Specialist in Washington, DC, and a Project Coordinator in Boulder, Colorado. Additional JOSS staff in Boulder provide web development, information technology, budget, and grant management support.
