The Global Historical Climatology Network daily (GHCNd) is an integrated database of daily climate summaries from land surface stations across the globe. GHCNd is made up of daily climate records from numerous sources that have been integrated and subjected to a common suite of quality assurance
The Next Generation Weather Radar (NEXRAD) system is a network of 160 high-resolution S-band Doppler weather radars jointly operated by the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the U.S. Air Force. The NEXRAD system detects precipitation and wind, and its
The U.S. Climate Normals are a large suite of data products that provide information about typical climate conditions for thousands of locations across the United States. Normals act both as a ruler to compare today’s weather and tomorrow’s forecast, and as a predictor of conditions in the near
On March 11, 2011, a magnitude 9.1 earthquake struck off the northeast coast of Honshu, Japan, generating a deadly tsunami.
The World Magnetic Model (WMM) is the standard model for navigation, attitude, and heading referencing systems that use the geomagnetic field. The WMM is also used for civilian applications, including navigation and heading systems. A new version of the model is updated every five years to address
Understand our billion-dollar weather and climate disasters information, how it’s calculated, what it tells us, and why it’s so important.
The Interactive Radar Map shows supplemental data in support of NCEI's Weather Radar Archive. The tool includes several unique features that allow users to select data from 1995–present for individual or multiple stations at varying altitudes.
NCEI provides access to the forecast data generated by the Global Forecast System (GFS) model, as well historical GFS data. The GFS is a National Centers for Environmental Prediction (NCEP) weather forecast model that generates data for dozens of atmospheric and land-soil variables, including
Though climate and weather are closely related, they aren't the same thing. The main difference between the two is time.
Learn about how and why the geomagnetic poles move, and access pole location data from 1590–2025.
The Department of Commerce certifies data maintained in the NCEI archive to meet the authentication requirements for records submitted as evidence in a court of law. This page details costs and procedures with accessing that data.
NCEI manages one of the largest environmental data archives in the world. The archive contains much of the data collected by NOAA scientists, observing systems, and research initiatives, and includes many different topics and disciplines. Who can submit data to the NCEI archive? NCEI accepts data
The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) is the most complete collection of surface marine data in existence. ICOADS offers surface marine data spanning from 1662 to present day. It also provides gridded monthly summary products on 2°x2° (back to 1800) and 1°x1° boxes
The newest version of the Surface Ocean Carbon Atlas (SOCATv2024) database is now available via NCEI.
