Meteorological and oceanographic data collected from the National Data Buoy Center Coastal-Marine Automated Network (C-MAN) and moored (weather) buoys during 2014-03 (NODC Accession 0117682)

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 March 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、海角与海滩、近岸岛屿以及海上平台上部署了约50座C-MAN观测站，并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远海水域中，布设了百余台系留（又称气象）浮标。

C-MAN与系留浮标的常规观测数据涵盖气压、风向、风速、阵风强度以及气温；部分C-MAN观测站还可配套测量海水温度、水位、海浪与相对湿度。系留浮标可采集海浪能量谱，NDBC据此计算有效波高、主波周期与平均波周期；此外，多数系留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资料中心（National Oceanographic Data Center，NODC）开展合作，共同归档C-MAN与系留浮标的观测数据。本次NODC存档数据集为该合作项目的组成部分，内含2014年3月采集的观测数据，存储格式为netCDF（第4版）文件。
