NCEI data upgrade will provide more modern, easier data access than ever before.
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 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
Though climate and weather are closely related, they aren't the same thing. The main difference between the two is time.
EMAG2 (Earth Magnetic Anomaly Grid 2-arc-minute resolution) is compiled from satellite, ship, and airborne magnetic measurements. Magnetic anomalies result from geologic features enhancing or depressing the local magnetic field. These maps increase knowledge of subsurface structure and composition
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 World Data Service for Paleoclimatology manages the International Tree-Ring Data Bank (ITRDB), the world's largest public archive of tree ring data. Oversight is provided by the ITRDB Advisory Committee. The ITRDB includes raw ring width, wood density, isotope measurements, and site growth index
Meteorologists and climatologists define seasons differently from “regular” or astronomical spring, summer, fall, and winter.
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
NCEI provides access to lightning flash summaries by county and state, gridded lightning frequency products, and other data derived from internal products. Data is available in standard formats through direct download, and web services that allow spatial and temporal subsetting. The National
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
The NOAA Merged Land Ocean Global Surface Temperature Analysis (NOAAGlobalTemp, formerly known as MLOST) combines long-term sea surface (water) temperature (SST) and land surface (air) temperature datasets to create a complete, accurate depiction of global temperature trends. The dataset is used to
The High Definition Geomagnetic Model 2026 release provides enhanced resolution and reduces uncertainty in complex drilling environments.
