    • Sea surface temperature and salinity from the Global Ocean Surface Underway Data (GOSUD) from 1980-01-03 to present

    Metadata Updated: March 5, 2026

    This collection contains the Global Ocean Surface Underway Data (GOSUD) from 1980-01-03 to present as submitted to NOAA/NCEI. The data includes information about sea surface temperature and salinity, in netCDF formatted files, obtained with the use of thermosalinographs (TSG) installed in a variety of ships. The datasets provided by the various contributors are collected and assembled by GOSUD, an initiative of the International Oceanographic Data and Information Exchange (IODE) of the Intergovernmental Oceanographic Commission (IOC) programme. All data are quality controlled and flagged by GOSUD following the GOSUD procedures and criteria. The measured variables or parameters include conductivity, sea surface salinity, sea surface water temperature (using internal sensor), water temperature (using external sensor, when available), latitude, longitude and time. The originator's data have different temporal resolutions ranging from three minute median filtered values to one hour point values. The spatial coverage of the dataset is global.

    This collection contains not only the latest version (v3.0) of GOSUD data, but also the previous versions of GOSUD (v1.0 and v2.0). GOSUD stopped maintaining and updating the v1.0 in 2015. The v2.0 data are still updated, but will be discontinued in the future. The v3.0 data are considered as the official dataset of GOSUD, and contains TSG data from 2000 onwards. Historical data collected before 2000 have not been upgraded to v3.0 and can only be found in v1.0 and v2.0. This collection is updated monthly.
