Comprehensive Ocean-Atmosphere Data Set (COADS), 2-Degree Standard and Enhanced Products, 1950-1997

Summary
Abstract: The Comprehensive Ocean-Atmosphere Data Set (COADS) is the most
extensive and widely used set of surface marine data currently
available for the world ocean back to 1854, the year marking the
beginning of an internationally organized system for recording
shipboard meteorological observations. COADS is the result of a
continuing cooperative project between the National Oceanic and
Atmospheric Administration (NOAA)-specifically its Environmental
Research Laboratories (ERL), National Climatic Data Center (NCDC), and
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 COADS is currently supported by the NOAA
Climate and Global Change Program and the NOAA Environmental Services
Data and Information Management (ESDIM) Program.

The COADS netCDF files are grouped according to the time period and
spatial domain covered, and the gridbox size. For data starting in
1950, the 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 limits, with
the observations limited (as nearly as practical) to those from
ships. In the "enhanced" products, the data have been edited using
broader 4.5 sigma limits to better represent extreme climate events,
with observations from ships and other in situ marine platforms.

The 2-degree data are separated into two periods. The first known as
the Release 1 products covers the period 1854 to 1949. The second
period 1950 to 1997 is coverd by the COADS 2-degree products. This
second period has both standard and enchanced products.

The COADS 2-Degree data is available from:
"http://www.cdc.noaa.gov/cdc/data.coads.2deg.html"

and

"ftp://ftp.cdc.noaa.gov/Datasets/coads/2degree/"
