The National Oceanic and Atmospheric Administration seeks to understand and predict changes in climate and weather and changes that affect coasts and oceans; shares its knowledge and information with others; and conserves and manages coastal and marine ecosystems and resources.

Establishment and Organization

On October 3, 1970, Reorganization Plan No. 4 of 1970 (5 U.S.C. app.) formed the National Oceanic and Atmospheric Administration (NOAA).

NOAA posts an organizational chart at the bottom of its "Organization" web page, in Portable Document Format (PDF), for viewing and downloading.

NOAA published its statement of functions, organization, and delegation of authority in the Federal Register on February 13, 1978 (43 FR 6128).


Science, service, and stewardship characterize NOAA's mission. Its researchers, scientists, and technicians study the atmosphere, the ocean, and the ecosystems associated with them; they integrate research and analysis; they observe and monitor; and they use modeling to predict the future state of complex systems. NOAA serves academic institutions, businesses, communities, and ordinary people by communicating and sharing its data, information, knowledge, and research. NOAA also applies its institutional know-how and science assets to the conservation and management of coastal and marine ecosystems and resources. The agency regulates and sustains marine fisheries and ecosystems, protects endangered species, restores habitats and ecosystems, conserves marine sanctuaries, responds to environmental emergencies, and assists with disaster recovery.

Marine and Aviation Operations

The Office of Marine and Aviation Operations manages the aviation safety, the small boat, and the NOAA diving programs. It also operates a fleet of specialized ships and aircraft that collect data and carry out research to support NOAA's mission, the Global Earth Observation System, and the Integrated Ocean Observing System—including flying "hurricane hunter" aircraft into the most turbulent storms to collect data critical for research.

National Coastal Resources

The National Ocean Service helps balance the Nation's use of coastal resources through research, management, and policy. The Service monitors the health of U.S. coasts by examining how human use and natural events affect coastal ecosystems. Coastal communities rely on the Service for information on natural hazards so they can reduce or eliminate destructive effects of coastal hazards. The Service assesses the damage caused by hazardous material spills and tries to restore or replace the affected coastal resources. The Service also protects beaches, water quality, wetlands, and wildlife. It provides a wide range of navigational products and data that help vessels move safely through U.S. waters, and it supplies the basic information for establishing the latitude, longitude, and elevation framework necessary for the Nation's mapping, navigation, positioning, and surveying activities.

National Environmental Satellite, Data, and Information

The National Environmental Satellite, Data, and Information Service operates the Nation's civilian geostationary and polar-orbiting environmental satellites. It also manages the largest collection of atmospheric, climatic, geophysical, and oceanographic data in the world. The Service develops and provides, through various media, environmental data for forecasts, national security, and weather warnings to protect life and property. These data are also used for energy distribution, global food supplies development, natural resources management, and rescuing downed pilots and mariners in distress.

National Marine Fisheries

The National Marine Fisheries Service supports the management, conservation, and sustainable development of domestic and international living marine resources and the protection and restoration of ecosystems. The Service helps assess the stock of the Nation's multi-billion-dollar marine fisheries, protect marine mammals and threatened species, conserve habitats, assist trade and industry, and conduct fishery enforcement activities.

National Weather

The National Weather Service (NWS) provides weather, water, and climate warnings and forecasts and data for the United States, its territories, and adjacent waters and ocean areas. Government agencies, the private sector, the general public, and the global community rely on NWS data and products to protect life and property. Working with partners in Government, academic and research institutions, and private industry, the Service responds to the needs of the American public through its products and services. NWS data and information support aviation, maritime activities, and other sectors of the economy, as well as wildfire suppression. The Service also helps national security efforts with long- and short-range forecasts, air quality and cloud dispersion forecasts, and broadcasts of warnings and critical information over the 800-station NOAA Weather Radio network.

Oceanic and Atmospheric Research

The Office of Oceanic and Atmospheric Research conducts research on air quality and composition, climate variability and change, weather, and coastal, marine, and Great Lakes ecosystems. The Office uses its own laboratories and offices to run research programs in atmospheric, coastal, marine, and space sciences, as well as relying on networks of university-based programs across the country.

Sources of Information

Archived Records

The "Guide to Federal Records in the National Archives of the United States" indicates that NOAA records have been assigned to record group 370.

Arctic Report Cards

Every year, NOAA publishes an Arctic Report Card as part of its efforts to track recent environmental changes relative to historical records.

Atmospheric Carbon Dioxide

Adding to the data record that C. David Keeling of the Scripps Institution of Oceanography started in 1958, NOAA continues to measure atmospheric carbon at the Mauna Loa Observatory in Hawaii.

The Earth System Research Laboratory's Global Monitoring Division has posted a 4-minute video showing 800,000 years of atmospheric carbon dioxide history.

Atmospheric Methane

The Earth System Research Laboratory's Global Monitoring Division has been measuring methane since 1983 at a globally distributed network of air sampling sites.

A recent NOAA study (APR 2019) concludes that long‐term measurements show little evidence for large increases in total U.S. methane emissions over the past decade.

Career Opportunities

A career at NOAA is a mission-oriented experience that centers on protecting natural resources, safeguarding the public, and strengthening the economy.

In 2020, NOAA ranked 111th among 411 agency subcomponents in the Partnership for Public Service's Best Places To Work Agency Rankings.

Climate Change

The Carbon Cycle Greenhouse Gases research area operates the global greenhouse gas reference network. Researchers measure the atmospheric distribution and trends of the main causes of climate change: carbon dioxide (CO2); methane (CH4); nitrous oxide (N2O); and carbon monoxide (CO) because it is an indicator of air pollution.

"The Power of Greenhouse Gases" web page presents examples of the excess heat that the Earth system is retaining. The amount of excess heat is sufficiently large to force climate change on a regional and global scale.
