Archived data related to recent or significant tsunami events from around the world.
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 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
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 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.
The World Ocean Database (WOD) is world's largest collection of uniformly formatted, quality controlled, publicly available ocean profile data. It is a powerful tool for oceanographic, climatic, and environmental research, and the end result of more than 20 years of coordinated efforts to
Though climate and weather are closely related, they aren't the same thing. The main difference between the two is time.
The International Best Track Archive for Climate Stewardship (IBTrACS) project is the most complete global collection of tropical cyclones available. It merges recent and historical tropical cyclone data from multiple agencies to create a unified, publicly available, best-track dataset that improves
Learn about how and why the geomagnetic poles move, and access pole location data from 1590–2025.
The Integrated Global Radiosonde Archive (IGRA) consists of radiosonde and pilot balloon observations from more than 2,800 globally distributed stations. The earliest data date back to 1905, and recent data become available in near real time from about 800 stations worldwide. Observations are
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
The NCEI Coastal Water Temperature Guide (CWTG) was decommissioned on May 5, 2025. The data are still available. Please see the Data Sources below.
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.
