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
In paleoclimatology, the study of past climates, scientists use “proxy” data to reconstruct past climate conditions.
In March 1993, the Storm of the Century struck the U.S. East Coast, claiming more than 270 lives and causing billions of dollars in damage.
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 Global Ensemble Forecast System (GEFS) is a weather model created by the National Centers for Environmental Prediction (NCEP) that generates 21 separate forecasts (ensemble members) to address underlying uncertainties in the input data such limited coverage, instruments or observing systems
The NOAA Space Weather Prediction Center (SWPC) provides multiple Space Weather Products including Forecasts, Reports, Summaries, Alerts, Models, and real-time data. NCEI archives and provides access to some SWPC data products for retrospective users. This video is of the WSA-Enlil prediction model
The World Ocean Atlas (WOA) is a collection of objectively analyzed, quality controlled temperature, salinity, oxygen, phosphate, silicate, and nitrate means based on profile data from the World Ocean Database (WOD). It can be used to create boundary and/or initial conditions for a variety of ocean
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 International Geomagnetic Reference Field (IGRF) is a standard mathematical description of the Earth's main magnetic field. It is used widely in studies of the Earth's deep interior, crust, ionosphere, and magnetosphere. While this web page is hosted at NOAA/NCEI, the model itself is developed
Annual temperatures across the contiguous U.S. (CONUS) averaged 54.6°F in 2025, which was 2.6°F above the 20th-century average and ranked as the fourth-warmest year in the 131-year record.
The North American Mesoscale Forecast System (NAM) is one of the National Centers For Environmental Prediction’s (NCEP) major models for producing weather forecasts. NAM generates multiple grids (or domains) of weather forecasts over the North American continent at various horizontal resolutions
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
NOAA's Weather and Climate Toolkit (WCT) is mapping and data conversion software. WCT is a free platform with source code that allows the visualization and export of local or remote weather and climate data including outputs from Radar, Satellites, and Modelling. Unique data conversion features
Local Climatological Data Version 2 (LCDv2) reports are concise monthly summaries of hourly, daily, and monthly weather station measurements. These summaries include temperature, precipitation, humidity, and common weather observation types. LCDv2 replaces LCDv1, providing some additional data
