Output fields from the NOAA WAVEWATCH III® wave model monthly hindcasts for 2014-10 (NODC Accession 0126373)

The NOAA WAVEWATCH III® hindcast dataset comprises output fields from the monthly WAVEWATCH III® hindcast model runs conducted at the National Centers for Environmental Prediction. Each model run produces a collection of files containing gridded fields comprised of input and mean wave parameters such as the significant wave height, directions, frequencies etc. Once per month, a wave simulation is carried out using restart files from the previous month and forced by hindcast wind products for the entire month. The resulting output data are transferred to NODC on a monthly basis. NODC assembles the series of files into monthly accessions to facilitate archival retention and public access. The fields are encoded in the standard GRIdded Binary version 2 (GRIB2) file format. Wave spectral data summaries are included, as well as detailed spectra at selected locations, in tabular text format. Nine different sets of output fields, corresponding to nine different grids used in the numerical simulations, are included. These include a global grid, as well as regional and coastal grids covering much of the North Atlantic and North Pacific oceans.

美国国家海洋和大气管理局（NOAA）WAVEWATCH III®后报数据集，包含美国国家环境预报中心（National Centers for Environmental Prediction）开展的月度WAVEWATCH III®后报模式运行所生成的输出场数据。每次模式运行均生成一组文件，其中包含由输入参数与平均波浪参数构成的格点场数据，参数涵盖有效波高、波向、波频等。每月开展一次波浪模拟，模拟将使用上月的重启文件，并以整月的后报风场产品作为强迫驱动项。生成的输出数据将按月移交至国家海洋数据中心（National Oceanographic Data Center，NODC）。国家海洋数据中心会将这一系列文件整合为月度入藏数据集，以方便档案留存与公众获取。上述格点场数据采用标准格点二进制第2版（GRIB2）文件格式编码存储。数据集同时包含波浪频谱数据摘要，以及以表格文本格式存储的选定位置详细频谱数据。本次数据集包含九组不同的输出场数据，分别对应数值模拟中使用的九套网格，其中涵盖全球网格，以及覆盖北大西洋、北太平洋大部分海域的区域与近岸网格。
