The objective of this project is to use individual ship reports from the COADS Compressed Marine Reports 5 to produce a global, high resolution data base for observational and modeling studies of the atmosphere-ocean system. In addition to basic quantities such as wind, sea surface temperature and humidity, this data set will include estimates of surface wind stress, latent and sensible heat fluxes, and short and long wave radiation fluxes. Particular attention will be paid to correct known biases associated with erroneous Beaufort scale and adjustment of the anemometer height to a standard 10 m reference level. The data sets will be produced in two different resolutions: 1) Global monthly mean summaries with 10 longitude by 10 latitude resolution, anomalies and climatology from 1945 to 1989; and 2) Global weekly mean summaries with 0.50 longitude by 0.50 latitude resolution, climatology form 1965 to 1989. These summaries will then be globally analyzed by essentially the same objective analysis scheme used in Levitus' Climatological Atlas of the World Oceans (1982). Raw monthly/weekly statistics will be made available to those users desiring to perform their own objective analysis. All products will be made widely available to the national and international scientific and operational communities with no restrictions. This project will provide better and more valuable data products for the use of the scientific community for observational studies of atmosphere-ocean system as well as forcing of the oceanic general circulation models, for air-sea interaction studies from interannual to decadal time scales, both in the tropics and/or extratropics and provide a more accurate surface marine climatology than presently exists.

本项目的目标是利用个人船舶 从COADS压缩海洋报告5的报告，以产生 用于观测和建模的全球高分辨率数据库 研究大气-海洋系统。 除了基本 风、海面温度和湿度等参数， 数据集将包括估计的表面风应力，潜在的， 感热通量、短波和长波辐射通量。 将特别注意纠正已知的偏见 与错误的博福特规模和调整的 风速计高度调整到标准的10米参考高度。 数据集将以两种不同的分辨率制作： 1)10经度× 10纬度的全球月平均摘要 1945 - 1989年的分辨率、距平和气候学; 2） 全球周平均值汇总，0.50经度× 0.50纬度 1965年至1989年的气候。 这些概要将 然后通过基本相同的目标进行全球分析 Levitus的《世界气候地图集》中使用的分析方案 海洋（1982年）。 将进行每月/每周原始统计 可供那些希望实现其自身目标的用户使用 分析. 所有产品将广泛提供给国家和 国际科学界和业务界， 限制. 这个项目将提供更好更有价值的数据 供科学界用于观测的产品 大气-海洋系统的研究以及 海气相互作用研究用海洋环流模式 从年际到十年的时间尺度，无论是在热带和/或 并提供更准确的海洋表面气候学 比目前存在的。
