Meteorological and oceanographic data collected from the National Data Buoy Center Coastal-Marine Automated Network (C-MAN) and moored (weather) buoys during 2012-01 (NODC Accession 0085139)

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 January 2012.

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）。NDBC已在灯塔、海角与滩涂、近岸岛屿以及海上平台上布设了约50座C-MAN观测站。此外，NDBC还在从西大西洋至夏威夷周边太平洋海域、从白令海至南太平洋的近岸与远海水域中，部署了百余台系泊（又称气象）浮标。

C-MAN与系泊浮标的观测数据通常涵盖气压、风向、风速、阵风以及气温；部分C-MAN观测站还可额外采集海水温度、水位、海浪以及相对湿度数据。系泊浮标会采集海浪能谱数据，NDBC可据此计算得到有效波高、主波周期与平均波周期。多数系泊浮标还可同步测量海浪传播方向。

NDBC与国家海洋数据中心（National Oceanographic Data Center, NODC）开展合作，对C-MAN与系泊浮标的观测数据进行归档存储。本次NODC入藏数据集即为该合作项目的组成部分，其包含2012年1月采集的网络通用数据格式（netCDF，版本4）文件。
