International Comprehensive Ocean-Atmosphere Data Set (ICOADS) Near-Real-Time (NRT) - Daily, Release 3.0.2

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: April 12, 2026 at 09:26 PM | Dataset Last Updated: May 15, 2023 at 12:00 AM
The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) is the world's most extensive surface marine meteorological data collection. Building on national and international partnerships, ICOADS provides a variety of user communities with easy access to many different data sources in a consistent format. Data sources range from early historical ship observations to more modern, automated measurement systems including moored buoys and surface drifters. Past versions of the ICOADS dataset have been published as monthly files while holding a daily version of the product for internal use only. NCEI has since developed a reformatted daily product of the dataset that now aligns with the monthly, ready for public use. The objective of this initiative is to sustain the quality and usability of this high-profile ICOADS product for stakeholders that have requested the need for an expanded product. ICOADS R3.0.2 Daily is now developed and released.
