NOAA Marine Environmental Buoy Database


ANNOUNCEMENT 15 August 2011: ATTENTION Matlab users! If you encounter problems opening netCDF files, please see click link below which will take you to a script written by John Evans, MathWorks. Running this script on files should permit Matlab to correctly open these files.

ANNOUNCEMENT 26 May 2011: NDBC is now submitting netCDF formatted files to NODC, instead of the previous F291 format.

As part of a data modernization effort, the National Data Buoy Center (NDBC) has updated the archival data file format of their Coastal-Marine Automated Network (C-MAN) stations and moored (weather) buoys to netCDF. This update facilitates inclusion of additional parameters, as well as improvements to the metadata. On 26 May 2011, NODC's NOAA Marine Environmental Buoy Database began disseminating NDBC’s archival data in these netCDF files, retroactively to the monthly January 2011 data. Data are available in both F291 and netCDF formats for January through March 2011. Data prior to January 2011 will remain in the F291 format.

Please address any questions or comments to NODC.buoy@noaa.gov.

This database holds wind, wave, and other marine data collected by the NOAA National Data Buoy Center (NDBC). The data are collected from NDBC moored buoys and from C-MAN (Coastal-Marine Automated Network) stations located on piers, offshore towers, lighthouses, and beaches. Parameters reported by both buoys and C-MAN stations include air temperature and pressure, wind speed and direction, wind gust, and sea surface temperature. The buoys (and a few C-MAN stations located on offshore towers) also report wave data, usually including wave height, wave period, and wave spectra. Since the late 1980s some buoys have reported directional wave spectra. NODC receives the data from NDBC on a monthly basis, generally 2-3 weeks after the last observation from the given month, and makes them available online.

The above interactive map and related files provide users with detailed information about the positions, period of record and other characteristics of the data in this NODC database. The NOAA Marine Environmental Buoy Database (only through December 1997) is available on CD-ROM from the online store or via User Services. However, all F291 Buoy Data in the NODC archive may be downloaded through this system. Note: file sizes range from 50 Kbytes to 1.4 Mbytes compressed (300 Kbytes to 5.5 Mbytes uncompressed).

    Latest data in the Buoy Data Archive is July 2014.
    Number of "Buoy Months" in the Archive is 45845.
    (Last updated August 26, 2014)

Note - two buoys 46023 and 46062 have associated id's, 46b23 and 46b62. The b data files contain observations taken by acoustic Doppler current profilers (ADCPs). Data records A (Descriptive Header Record) and E (Subsurface Current Data Record) are used in the files. The "new" buoy id's are treated like all other buoys in that they have their own inventory pages.
