The National Centers for Environmental Information (NCEI) is a U.S. government agency that manages one of the world's largest archives of atmospheric, coastal, geophysical, and oceanic data. The current director is Deke Arndt.
NCEI is operated by the
National Environmental Satellite, Data, and Information Service (NESDIS), an office of the
National Oceanic and Atmospheric Administration (NOAA), which operates under the
U.S. Department of Commerce.
In addition to archiving data, NCEI develops products and services that make data readily available to scientists, government officials, the business community, academia, non-governmental organizations, and the general public.
NCEI provides environmental data, products, and services covering the depths of the ocean to the surface of the Sun.
History
Formation
NCEI was created in 2015 from the merger of three NOAA data centers:
*
National Climatic Data Center
The United States National Climatic Data Center (NCDC), previously known as the National Weather Records Center (NWRC), in Asheville, North Carolina, was the world's largest active archive of weather data.
In 2015, the NCDC merged with two other ...
(NCDC)
*
National Geophysical Data Center (NGDC)
*
National Oceanographic Data Center (NODC), which includes the National Coastal Data Development Center (NCDDC)
NCEI was established by the
Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235 in response to increasing demand for environmental information. The organization was created by merging the three existing NOAA National Data Centers with the goal of streamlining the collection and preservation of environmental data.
The merger, which came in response to increasing demand for environmental information, was intended to make NOAA's data more useful through the application of consistent
data stewardship practices across all science disciplines. NCEI works with the
ISC World Data System to make data free and accessible.
Hurricane Helene
In September, 2024, the NCEI headquarters in
Asheville were buffeted by storm conditions and flooding from
Hurricane Helene. Severe damage was done to infrastructure, limiting network services and website availability. Archived data was rendered inaccessible, certain webpages suffered limited availability, and the monthly climate reports for September were postponed. They confirmed on October 4th that all data products, however, were safe.
Data and services

The NCEI
archive
An archive is an accumulation of historical records or materials, in any medium, or the physical facility in which they are located.
Archives contain primary source documents that have accumulated over the course of an individual or organ ...
contains more than 60
petabytes of data, equivalent to more than 700 million filing cabinets filled with documents. NCEI offers users access to tens of thousands of datasets and hundreds of products. Data are collected by
NOAA, other agencies and departments of the U.S. government, as well as by other institutions, organizations, and governments around the world.
Environmental data are collected from many sources, including
satellite
A satellite or an artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body. They have a variety of uses, including communication relay, weather forecasting, navigation ( GPS), broadcasting, scient ...

NCEI Subject Matter Experts (SMEs) collaborate on national and international research projects. In 2022, they collaborated with scientists from across the globe to produce world-class research and authored more than 90 papers in peer-reviewed journals. Areas of study were as varied as the environmental data housed at NCEI:
hurricanes,

NCEI data users
NCEI resources are used for scientific research and commercial applications in many fields, including agriculture, forestry, marine and coastal ecosystems, tourism, transportation, civil infrastructure, energy, transportation, water resources, energy, health, insurance, litigation, and national security.
For example, retail and manufacturing businesses use climate data to assess how weather has influenced past sales so they can better plan for the future. Corn farmers rely on NCEI data to decide how much fertilizer to apply. The reinsurance industry—which offers insurance to insurance companies—uses NCEI data to determine risks associated with natural disasters. Cattle ranchers use NCEI's weekly U.S. Drought Monitor to make decisions about land management, herd size, and feed purchases. The freight railway industry uses a number of NCEI products—including Local Climatological Data, Integrated Surface Daily Database, and
Global Historical Climatology Network—to predict where tracks might be blocked by landslides and to help trains avoid the path of severe storms. U.S. fishing boats use NCEI ocean and coastal data to determine where fishing conditions are most promising. The third-party weather service industry uses NCEI data to create customized forecasts and other tools to serve a wide range of clients, such as transportation companies seeking to build facilities where fog or snow is less likely to create problems.
