Meteorological and oceanographic data collected from the National Data Buoy Center Coastal-Marine Automated Network (C-MAN) and moored (weather) buoys during May 2015 (NCEI Accession 0129415)

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 May 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（Coastal-Marine Automated Network, C-MAN）。目前，NDBC已在灯塔、海岬与海滩、近岸岛屿以及海上平台上布设了约50座C-MAN观测站；同时在从西大西洋经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，部署了超过100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、阵风及气温；不过部分C-MAN观测站还可额外测量海水温度、水位、海浪与相对湿度。系泊浮标可采集海浪能谱，NDBC可据此推导有效波高、主波周期与平均波周期。此外，多数系泊浮标还可测量海浪传播方向。 NDBC与国家海洋资料中心（National Oceanographic Data Center, NODC）正合作对上述C-MAN及系泊浮标的观测数据进行归档存储。本次NODC归档数据集即为此合作项目的组成部分，其包含2015年5月采集的netCDF（第4版）格式数据文件。
