"In January 1981, a cooperative project was planned to create a consistent and easily used historical record of surface marine data for the period 1854-1979 (Woodruff, et al., 1987). Members of this project were the National Climatic Data Center (NCDC), Environmental Research Laboratories, the cooperative Institute for Research in Environmental Sciences, and the National Center for Atmospheric Research. The culmination of four years of work resulted in the Comprehensive Ocean-Atmosphere Data Set (COADS) (Slutz, et al., 1985, hereafter referred to as COADS Release 1)."
"One of the many products of COADS was a unique set of surface marine ship reports in a modified TD-1129 format covering the period 1854-1979 (TD-1170). This document provides information only for COADS pre-1970s surface marine data. A similar COADS product covering the period 1970-1979 (TD-1129) is described in a Marine Data Users Reference, 1970-current (NCDC, 1986). Data Prior to 1854 is contained in the Maury collection."
"Products now available in a first release from this Comprehensive Ocean-Atmosphere Data Set (COADS) include fully quality-controlled (trimmed) reports and summaries. Global marine data observed during 1854-1979, primarily by ships-of-opportunity, have been collected, edited, and summarized statistically for each month of the period, using 2 degree latitude x 2 degree longitude boxes. Each of the 70 million unique reports contain 28 elements of weather, position, etc., as well as flags indicating which observations were statistically trimmed. The summaries give l4 statistics, such as the median and mean, for each of eight observed variables of air and sea surface temperatures, wind, pressure, humidity, and cloudiness, plus ll derived variables. Relatively noisy (untrimmed) individual reports and summaries (giving l4 statistics for each of the eight observed variables) are available for investigators who prefer their own quality control. Two other report forms, inventories, and decade-month summaries are among the other products available. FORTRAN 77 software available to help read 'packed binary' data products and processing details, such as the method of identifying duplicate reports, are also available."
"The Compressed Marine Reports contain 28 frequently used parameters, omitting individual ship numbers. Statistical outliers are flagged. The entire set is stored in binary format. Refer to COADS Release 1, Supplement E, for further details. The Long Marine Reports contain the complete observational record of the platform which contributed the data, as well as quality flags. The data are stored in a hybrid format of packed binary and character. Further information on format is available in COADS Release 1, Supplement F. Character-formatted Long Marine Reports, a subset of the Long Marine Reports, are stored in ASCII character format, more fully described in Supplement I of COADS, Release 1."
"The Decadal and Monthly Summaries are averaged by decade and month over either 10 x 10 or 2 x 2 latitude-longitude boxes. In trimmed versions of these summaries statistical outliers and data located over land have been removed. The data are stored in packed binary format. Further details can be obtained from COADS Release 1, Supplement A."
"Monthly Summary Trimmed and Untrimmed Groups (the former is the only kind presented here in LDEO -- AK) contain fewer variables and fewer statistical parameters than the monthly summaries. The sort is by year, month and 2 degree latitude-longitude box. This product is the most compact and generally the most convenient to use for studies involving only a few variables and statistical parameters. COADS Release 1, Supplement B gives further details."
