Meteorological and oceanographic data collected from the National Data Buoy Center Coastal-Marine Automated Network (C-MAN) and moored (weather) buoys during 2005-10 (NODC Accession 0002436)

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.

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（National Weather Service）搭建了海岸海洋自动观测网络（Coastal-Marine Automated Network，C-MAN）。该中心已在灯塔、海角、海滩、近岸岛屿以及海上平台上布设了约50座C-MAN站点。此外，国家数据浮标中心还在从西大西洋至夏威夷周边太平洋、从白令海至南太平洋的近岸与外海水域中，部署了超过100套锚定浮标（moored buoy，又称气象浮标）。C-MAN站点与锚定浮标的观测数据通常涵盖气压、风向、风速与阵风以及气温；不过部分C-MAN站点还具备海水温度、水位、海浪以及相对湿度的测量能力。锚定浮标会采集海浪能量谱，国家数据浮标中心借此计算得到有效波高、主波周期以及平均波周期。此外，多数锚定浮标还可观测海浪传播方向。国家数据浮标中心与国家海洋数据中心（National Oceanographic Data Center，NODC）正合作对C-MAN站点及锚定浮标的观测数据进行归档存储。
