Meteorological and oceanographic data collected from the National Data Buoy Center Coastal-Marine Automated Network (C-MAN) and moored (weather) buoys during December 2014 (NODC Accession 0125264)

The National Data Buoy Center (NDBC) established the Coastal-Marine Automated Network (C-MAN) for the National Weather Service in the early 1980's. NDBC has installed approximately 50 C-MAN stations on lighthouses, at capes and beaches, on near shore islands, and on offshore platforms. NDBC has deployed over 100 moored (a.k.a., weather) buoys in coastal and offshore waters from the western Atlantic to the Pacific Ocean around Hawaii, and from the Bering Sea to the South Pacific. C-MAN and moored buoy data typically include barometric pressure, wind direction, speed and gust, and air temperature; however, some C-MAN stations are equipped to also measure seawater temperature, water level, waves, and relative humidity. Moored buoys measure wave energy spectra from which NDBC derives significant wave height, dominant wave period, and average wave period. In addition, many moored buoys measure the direction of wave propagation.

In collaboration, NDBC and the National Oceanographic Data Center (NODC) are archiving these data from C-MAN and moored buoys. This NODC Accession is part of the collaboration and it contains netCDF (version 4) files with the data collected during December 2014.

国家数据浮标中心（National Data Buoy Center，NDBC）于20世纪80年代初为美国国家气象局建成了海岸海洋自动观测网络（Coastal-Marine Automated Network，C-MAN）。目前，NDBC已在灯塔、海角、海滩、近岸岛屿及海上平台布设约50个C-MAN观测站；同时在西大西洋至夏威夷周边太平洋海域、白令海至南太平洋的近岸与外海水域，部署了100余套系泊浮标（moored buoy，又称气象浮标）。C-MAN观测站与系泊浮标的常规观测数据涵盖气压、风向、风速、阵风及气温；部分C-MAN站还可额外测量海水温度、水位、海浪及相对湿度。系泊浮标会采集海浪能谱，NDBC借此计算得到有效波高、主波周期与平均波周期；此外，多数系泊浮标还可监测波浪传播方向。

NDBC与国家海洋资料中心（National Oceanographic Data Center，NODC）合作开展上述C-MAN观测站及系泊浮标的观测数据归档工作。本次NODC入藏编号属于该合作项目的一部分，其包含2014年12月采集的netCDF（版本4）格式数据文件。
