The Global Forecast System (GFS) is a National Centers for Environmental Prediction (NCEP) weather forecast model that generates data for dozens of atmospheric and land-soil variables, including temperatures, winds, precipitation, soil moisture, and atmospheric ozone concentration. The system
On March 11, 2011, a magnitude 9.1 earthquake struck off the northeast coast of Honshu, Japan, generating a deadly tsunami.
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
Learn about the legacy of Dr. George Washington Carver, one of the prominent Black scientists of the early 20th century.
2025 ranked as the third-warmest year in NOAA’s 176-year record, with a global surface temperature 2.11°F (1.17°C) higher than the 20th-century baseline.
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
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
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
Though climate and weather are closely related, they aren't the same thing. The main difference between the two is time.
The NCEI Coastal Water Temperature Guide (CWTG) was decommissioned on May 5, 2025. The data are still available. Please see the Data Sources below.
Every February 2, we anxiously await groundhog Punxsutawney Phil’s prediction of spring’s arrival, but how accurate is he?
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 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
