Meteorological and oceanographic data collected from the National Data Buoy Center Coastal-Marine Automated Network (C-MAN) and moored (weather) buoys during October 2015 (NCEI Accession 0137949)

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 October 2015.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搭建了海岸海洋自动观测网络（Coastal-Marine Automated Network，C-MAN）。目前，NDBC已在灯塔、海角与海滩、近岸岛屿以及海上平台上部署了约50座C-MAN观测站。同时，NDBC还在从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远海水域中，布设了超过100台锚定（又称气象）浮标。C-MAN网络与锚定浮标的观测数据通常涵盖气压、风向、风速、阵风强度以及气温；部分C-MAN观测站还额外配备了海水温度、水位、海浪以及相对湿度的监测设备。锚定浮标会采集海浪能量谱数据，NDBC可据此推算有效波高、主波周期与平均波周期。此外，多数锚定浮标还可监测海浪传播方向。 NDBC与美国国家海洋资料中心（National Oceanographic Data Center，NODC）合作，对上述C-MAN网络与锚定浮标的观测数据进行归档存储。本NODC归档数据集（NODC Accession）属于该合作项目的一部分，其包含2015年10月采集的观测数据，存储格式为netCDF（版本4）。
