The National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) was designed and executed as a global, high-resolution, coupled atmosphere-ocean-land surface-sea ice system to provide the best estimate of the state of these coupled domains over the 32-year period of record from January 1979 to March 2011. It has been extended as an operational real-time product. The data in Earth Engine are only present starting from December 13, 2018.

Forecasts are initialized four times per day (0000, 0600, 1200, and 1800 UTC). We ingest only a subset of bands from files matching cdas1.t??z.pgrbh03|00.grib2 i.e. files of only 0-hour and 3-hour forecasts as the others are omitted. The forecast length is indicated by the 'forecast_hour' metadata field.

Some images contain only a subset of bands. Using this dataset with both "00" and "03" forecast types will require you to cast the bands across the collection.

美国国家环境预测中心（NCEP）的气候预测系统再分析（CFSR）是作为一个全球性的、高分辨率的、大气-海洋-陆地表面-海冰耦合系统设计和执行的，以提供1979年1月至2011年3月32年记录期间这些耦合领域状态的最佳估计。它已被扩展为一个实用的实时产品。地球引擎中的数据只从2018年12月13日开始出现。

预测每天初始化四次（0000、0600、1200和1800 UTC）。我们只从匹配cdas1.t??z.pgrbh03|00.grib2的文件中摄取一个波段子集，即只摄取0小时和3小时的预报文件，因为其他的都省略了。预报长度由 "预报_小时 "元数据字段表示。

有些图像只包含一个波段的子集。使用这个数据集的 "00 "和 "03 "预报类型将要求你在整个集合中投下波段。

The National Centers for Environmental Prediction (NCEP) Climate Forecast System (CFS) is a fully coupled model representing the interaction between the Earth's atmosphere, oceans, land, and sea ice. CFS was developed at the Environmental Modeling Center (EMC) at NCEP. The operational CFS was upgraded to version 2 (CFSv2) on March 30, 2011.

Forecasts are initialized four times per day (0000, 0600, 1200, and 1800 UTC). This is the same model that was used to create the NCEP Climate Forecast System Reanalysis (CFSR), and the purpose of the CFSv2 dataset is to extend CFSR. We ingest only a subset of bands from files matching cdas1.t??z.sfluxgrbf06.grib2.

For more information about CFS, please see the CFS NOAA site.
