International Comprehensive Ocean-Atmosphere Data Set (ICOADS)
As the result of a US project starting in 1981, available global surface marine data from the late 17th century to date have been assembled, quality controlled, and made widely available to the international research community in products of the Comprehensive Ocean-Atmosphere Data Set (COADS). A new name, International COADS (ICOADS), was agreed in 2002 to recognize the multinational input to the blended observational database and other benefits gained from extensive international collaboration, while maintaining continuity of identity with COADS, which has been widely used and referenced.
The original COADS project, and the continuing US contribution toward the new international database, ICOADS, is the result of a cooperative project between the National Oceanic and Atmospheric Administration (NOAA)--specifically its Earth System Research Laboratory (ESRL), its National Climatic Data Center (NCDC), and the Cooperative Institute for Research in Environmental Sciences (CIRES, conducted jointly with the University of Colorado)--and the National Science Foundation's National Center for Atmospheric Research (NCAR). The NOAA portion of ICOADS is partially funded by the NOAA Climate Program Office (CPO).
ICOADS data are made available in two primary forms:
Release 2.5 observations are available for 1662-2007 (261 million individual marine reports), 2° monthly summaries for 1800-2007, and 1° summaries for 1960-2007. In addition, preliminary observations and monthly summaries are available from 2008 forward (updated monthly, and lagging real-time by 2-6 weeks). These data and summary products are drawn from two separate archives:
The observations and monthly summary products currently offered to users are all from ICOADS.DM through the end of 2007. That official Release 2.5 period is followed by preliminary observations and monthly summaries based on the ICOADS.RT archive.
Update plans are as follows:
