National Center for Atmospheric Research (U.S.)

The National Center for Atmospheric Research (NCAR ) is a federally funded research and development center headquartered in Boulder, Colorado, United States. Founded in 1960, NCAR is sponsored by the National Science Foundation (NSF) and managed by the University Corporation for Atmospheric Research (UCAR). NCAR's laboratories focus on topics within Earth system science, such as climate science, meteorology, atmospheric chemistry, the Sun and space weather, and environmental and societal impacts of weather and climate. Its laboratories provide the scientific community with specialized instrumentation, research aircraft, supercomputers, atmospheric models, and datasets for conducting research in Earth system science. NCAR manages multiple facilities, including the Mesa Laboratory headquarters in Boulder, Colorado; the NCAR-Wyoming Supercomputing Center in Cheyenne, Wyoming; and the Mauna Loa Solar Observatory on the island of Hawai'i in the state of Hawaii. In December 2025, Office of Management and Budget Director Russ Vought announced the planned closure of NCAR, alleging climate alarmism.
