International Comprehensive Ocean-Atmosphere Data Set (ICOADS) Near-Real-Time (NRT) - Monthly, Releases 3.0.2 and 3.0.3

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 10, 2026 at 10:05 PM | Dataset Last Updated: March 01, 2022 at 12:00 AM
The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) Near-Real-Time (NRT) product includes both versions 3.0.2 and 3.0.3. The new version includes blended preliminary NRT observations from ships and buoys and other platforms distributed in Traditional Alphanumeric Code (TAC) and Binary Universal Form for the Representation of meteorological data (BUFR) formats collected from the WMO Global Telecommunications System (GTS). The data are converted to the ICOADS common format, the International Maritime Meteorological Archive (IMMA) format, quality controlled, and duplicates removed for the final product. Marine meteorological and near-surface oceanographic parameters are provided. Spatial coverage is global, and the current period of record for these files is from July 2025 to the most current, complete month.
