Real-Time and Historic LEVEL 1 Data

Buoy data files are updated daily and made available individually via the link below. Values provided are confined to surface temperature, atmospheric temperature, and barometric pressure when these values are available. All buoy files contain at least a date and position. Buoys that are no longer reporting remain available on this page:

Buoy data formatted as csv are also available via ftp. The files are organized in folders based on the year of deployment.

  • Full Resolution Data (typically hourly) is available for buoys deployed since 2008. Both currently active and silent buoys are included.

  • 3 hourly resolution data is available from 1979 to 2016:

  • Daily Full Resolution Data is available from 2009 to present. Each file contains data from all buoys on a given date. Data includes: BuoyID, year, hour, minute, Day of Year, Position Day of year, latitude, longitude, Barometric Pressure, Surface Temp, and Atmospheric Temp.

    LEVEL 2 Data

    Once a buoy has stopped reporting for at least six months, light processing is performed on the data. This processing consists primarily of removing data prior to deployment, and eliminating obvious spikes. For some early buoys a correction for temperature "wrap-around" was also necessary. "Wrap-around" is when a buoy's temperature drops below the buoy's lower limit and then "wraps" to its upper limit. For example, say -5C is a buoys lower limit, and 60C is its upper limit. Then a temperature of -6C will be reported as 59C, and a temperature of -7C will report as 58C. The accuracy of the data has not been determined.

    IABP Datasets

    The following datasets are described in IABP Buoy Reports and are also available from the National Snow and Ice Data Center (NSIDC). NSIDC also maintains pages which describe the data and data processing techniques in greater detail. To see these pages, click here.
