Output fields from the NOAA Atlantic Real-Time Ocean Forecast System (RTOFS) for 2016-07-01 to 2016-07-31 (NCEI Accession 0156232)

The NOAA Atlantic Real-Time Ocean Forecast System (RTOFS) dataset comprises output fields from the daily operational RTOFS model runs conducted at the National Centers for Atmospheric Prediction. Each model run produces a series of gridded fields containing results of model computations for ocean temperature, salinity, currents, sea-surface height, and possibly other properties. The fields are encoded in the standard GRIdded Binary (GRIB) file format. NCEI compiles a series of files into monthly accessions to facilitate archival storage and public access. Two different sets of output fields are included: 1) daily 3-dimensional fields reported on the model's native hybrid (isopycnal plus z-level) vertical coordinates (note: prior to June 6, 2007, these fields are interpolated to z-levels); and 2) hourly fields reported for the surface level only. Each daily model run produces a 24-hr hindcast as well as forecasts out to 120 hours.

美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）大西洋实时海洋预报系统（Real-Time Ocean Forecast System, RTOFS）数据集，包含美国国家大气预测中心（National Centers for Atmospheric Prediction）每日运行的业务化RTOFS模式所产出的输出场。每次模式运行均会生成一系列格点场，涵盖海洋温度、盐度、海流、海面高度及其他潜在海洋要素的模式计算结果。上述格点场采用标准二进制格点（GRIdded Binary, GRIB）文件格式进行编码。国家环境信息中心（National Centers for Environmental Information, NCEI）将多份文件整合为月度数据集包，以便于归档存储与公共访问。该数据集包含两类输出场：1）基于模式原生混合（等密度面加z-level）垂直坐标系输出的每日三维格点场（注：2007年6月6日之前的此类场已被插值至z-level垂直层）；2）仅针对表层输出的逐小时格点场。每次每日模式运行都会生成24小时的后报结果，以及时效长达120小时的预报结果。
