attribute NC_GLOBAL summary String The data being submitted to NODC contain information about temperature and salinity obtained with the use of thermosalinographs (TSG) installed in ships of the NOAA fleet and other cargo and cruise ships. The data is transmitted to AOML/NOAA in real-time and submitted to a quality control procedure developed at AOML based on the Global Ocean Surface Underway Data Pilot Project (GOSUD) real-time control test. Data approved in these tests are submitted to the GTS. The data set submitted to NODC for distribution constitute the complete data set received by AOML with the corresponding flags after the quality control.
