NOAA CDR 计划的 CDR 官方分发点是 NOAA 的国家气候数据中心，该中心根据美国总统关于“开放数据政策”的备忘录中所述的美国开放数据政策和实践，并根据 2013 年 5 月 9 日的行政命令“将开放和机器可读性作为政府信息的默认新标准”，持续提供开放访问权限并积极管理 CDR 软件包和相关信息。根据这些政策，CDR 数据集是非专有的，可公开获取，并且对其使用没有任何限制。如需了解详情，请参阅 Fair Use of NOAA's CDR Data Sets, Algorithms and Documentation PDF 文件。

First a near\nreal-time preliminary version is released with a lag of 1 day, and a final\nversion with a lag of 14 days. The final version uses extra days for\nsmoothing, and zonal bias correction in addition to replacing the\npreliminary version.\n\nBands\n\n\n**Pixel Size**\n\n27830 meters\n\n**Bands**\n\n| Name | Units | Min | Max | Scale | Pixel Size | Description |\n|--------|-------|---------|--------|-------|------------|---------------------------------------------------------------------------|\n| `sst` | °C | -180\\* | 3764\\* | 0.01 | meters | Daily sea surface temperature |\n| `anom` | °C | -1887\\* | 1902\\* | 0.01 | meters | Temperature anomaly; the daily OISST minus a 30-year climatological mean. |\n| `ice` | % | 1\\* | 100\\* | 0.01 | meters | Seven-day median of daily sea ice concentrations. |\n| `err` | °C | 11\\* | 171\\* | 0.01 | meters | Estimated error; standard deviation of analyzed sea surface temperature. |\n\n\\* estimated min or max value\n\nImage Properties\n\n**Image Properties**\n\n| Name | Type | Description |\n|--------|--------|------------------------------|\n| status | STRING | 'provisional' or 'permanent' |\n\nTerms of Use\n\n**Terms of Use**\n\nThe NOAA CDR Program's official distribution point for CDRs is NOAA's\nNational Climatic Data Center which provides sustained, open access and\nactive data management of the CDR packages and related information in\nkeeping with the United States' open data policies and practices as\ndescribed in the President's Memorandum on \"Open Data Policy\" and pursuant\nto the Executive Order of May 9, 2013, \"Making Open and Machine Readable\nthe New Default for Government Information\".
