COADS Data Online at NOAA Climate Diagnostics Center CDC | CIRES |
NCAR | NCDC The Comprehensive Ocean-Atmosphere Data Set (COADS) is the
most extensive collection of surface marine data available for the
world ocean over the past two centuries. COADS is the result of a
continuing cooperative project between NOAA and NCAR. Please refer to
the COADS Website for more information about COADS, and associated
metadata. NOAA's Climate Diagnostics Center (CDC) provides online
access to monthly summary statistics for 2° latitude x 2°
longitude boxes (and for 1°x1° boxes starting in 1960)
selected from the full set of summary and observational products
available at NCAR or NCDC. These online data are distributed in the
netCDF format using metadata conventions developed at CDC. Among the
conventions are the attributes scale_factor and add_offset, which are
used to pack floating-point data into 16-bit integers (for more
details, including information about small numerical biases in the
resulting netCDF data, please see this webpage). The netCDF files can
be downloaded by anonymous FTP or by following hyperlinks below. CDC
can supply Fortran code and can suggest other software that can be
used to display and analyze the COADS data. The netCDF files are
subdivided into "standard" and "enhanced" products, which reflect the
"trimming" (quality control) procedure used and the data mixture. In
the standard products, the data have been edited using climatological
3.5 standard-deviation (sigma) limits, with the observations limited
(as nearly as practical) to those from ships. In the "enhanced"
products, in contrast, the data have been edited using broader 4.5
sigma limits to better represent extreme climate events, with
observations from ships plus from other in situ marine platform types
(e.g., drifting and moored buoys). For data starting in 1960, the
netCDF files are further subdivided by gridbox size (2°x2° or
1°x1° boxes) and spatial domain, with the 1°x1°
summaries available in global and equatorial formats. The equatorial
products cover the latitude band 10.5°N to 10.5°S, and are
global with respect to longitude. In contrast to the global
1°x1° boxes, the equatorial 1°x1°boxes are shifted
half a degree in latitude (only) in comparison to the global domain,
such that the center-latitude of the central row of boxes is the
equator (e.g., 0-1°E, 0.5°S-0.5°N). Both the global and
equatorial formats have a standard and enhanced product. Please note:
If you acquire COADS data products from CDC, we ask that you
acknowledge us in your use of the data. This may be done by including
text such as COADS data provided by the NOAA-CIRES Climate Diagnostics
Center, Boulder, Colorado, USA, from their Web site at
http://www.cdc.noaa.gov/ in any documents or publications using these
data. We would also appreciate receiving a copy of the relevant
publications. This will help CDC to justify keeping COADS products
freely available online in the future. Thank you! The following pages
provide access to the data by box size, and selections within these
pages provide access to the further subdivisions of data by spatial
domain and product type (as applicable): COADS 2°x2° products
(1800-1997)  (Including a correction.)
