The NOAA 1/4 degree daily Optimum Interpolation Sea Surface Temperature (OISST) provides complete ocean temperature fields constructed by combining bias-adjusted observations from different platforms (satellite, ships, buoys) on a regular global grid, with gaps filled in by interpolation. Satellite data from the Advanced Very High Resolution Radiometer (AVHRR) provides the main input which permits the high temporal-spatial coverage beginning in late 1981 to the present.
The OISST dataset has a single day's data processed twice. First a near real-time preliminary version is released with a lag of 1 day, and a final version with a lag of 14 days. The final version uses extra days for smoothing, and zonal bias correction in addition to replacing the preliminary version.
NOAA每天1/4度的最佳内插海面温度(OISST)提供了完整的海洋温度场，它是通过将不同平台(卫星、船舶、浮标)的偏差调整后的观测数据在全球常规网格上进行组合，并通过内插法填补空白。来自高级甚高分辨率辐射计（AVHRR）的卫星数据提供了主要的输入，使得从1981年末至今的时间-空间覆盖率很高。
OISST数据集对一天的数据进行两次处理。首先发布的是滞后1天的近实时初步版本，以及滞后14天的最终版本。最终版本除了取代初步版本外，还使用额外的天数进行平滑处理和区域偏差校正。

数据说明：
The NOAA CDR Program’s official distribution point for CDRs is NOAA’s National Climatic Data Center which provides sustained, open access and active data management of the CDR packages and related information in keeping with the United States’ open data policies and practices as described in the President's Memorandum on "Open Data Policy" and pursuant to the Executive Order of May 9, 2013, "Making Open and Machine Readable the New Default for Government Information". In line with these policies, the CDR data sets are nonproprietary, publicly available, and no restrictions are placed upon their use. For more information, see the Fair Use of NOAA's CDR Data Sets, Algorithms and Documentation pdf.
