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
NCEI provides several different ways to search for, discover, and access metadata. Metadata is also used to enhance search and discovery for data access software.
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 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
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 ETOPO Global Relief Model integrates topography, bathymetry, and shoreline data from regional and global datasets to enable comprehensive, high resolution renderings of geophysical characteristics of the earth’s surface. The model is designed to support tsunami forecasting, modeling, and warning
On March 11, 2011, a magnitude 9.1 earthquake struck off the northeast coast of Honshu, Japan, generating a deadly tsunami.
Learn about how and why the geomagnetic poles move, and access pole location data from 1590–2025.
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
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
During 2023, the average contiguous U.S. temperature was 54.4°F, 2.4°F above the 20th-century average.
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 Integrated Surface Database (ISD) is a global database that consists of hourly and synoptic surface observations compiled from numerous sources into a single common ASCII format and common data model. ISD integrates data from more than 100 original data sources, including numerous data formats
The NOAA 1/4° Daily Optimum Interpolation Sea Surface Temperature (OISST) is a long term Climate Data Record that incorporates observations from different platforms (satellites, ships, buoys and Argo floats) into a regular global grid. The dataset is interpolated to fill gaps on the grid and create
