Two Argo Global Data Assembly Centers (GDACs), the U.S. GODAE (Global Ocean Data Assimilation Experiment) Argo server and the French IFREMER (Institute for Research and Exploitation of the Sea) Argo server, are established to assemble the near real-time Argo data and provide them to the Argo users in a timely manner GDAC data. For users interested in using the official Argo NetCDF files, the GDACs should be the route to access Argo data. Both GDACs offer access to the complete Argo data collection as managed by the Argo Data Management Team, including float metadata, detailed trajectory data, profile data and technical data all in NetCDF format. It is important to understand the naming system of the files. US Argo Data Assembly Center Operations. Floats used in the international Argo program are free drifting profiling instruments distributed over the global oceans. These floats measure temperature and salinity in the upper 2,000 meters. Almost 3,000 of these Argo floats have been deployed providing 100,000 temperature/salinity profiles and. The Argo Ocean Profiling Network is a global ocean observing system developed to address the lack of data coverage in parts of the world ocean, as well as the need for regular capture intervals to enable both short and long-term climate predictions. NCEI operates and manages the Global Argo Data Repository (GADR), which provides long term archive services to store and preserve data

It also considers the sensor drift with QC algorithms as described by Gaillard et al. [2008], however their analysis is only limited in the Atlantic Ocean Argo data management: • DACs (Data Assembly Centers) receive the data via satellite trans-mission, and decode and quality control the data according to a set of 19 real-time automatic tests agreed upon within Argo. Erroneous data are flagged, if possible corrected, and then passed to the two global data centers and on to the Global sensors on Argo CTDs supplied since the beginning of the Argo program. Both types of pressure sensors exhibit drift in offset across their measurement range that is apparent in surface pressure data. The data set presented was downloaded from the Argo Global Data Assembly Center and is compiled from float A defining aspect of Argo is that all data are reported in near real-time to meteorological forecasting centres and to the two Argo Global Data Assembly Centers (GDACs, localized in the USA and France), from which the accumulated data are made freely available without limitation to all the users

The SAO17 data set was created from historical CTD station data, Argo data, and Nansen bottle data and was gridded with bathymetry-dependent decorrelation scales. The derived ASC axis generally locates within the depth range 1,000-2,000 m, while the derived SB typically locates within the 3,000-4,000 m developed and used in research at LPO in close collaboration with Coriolis data centre, one of the Argo Global Data Assembly Center (GDAC).

Since Argo observations began, changes in SAMW formation rates and properties have driven the most significant anthropogenic heat uptake by the global ocean anywhere on the planet, accounting for 67-98% of the net global ocean heat uptake, which itself is the dominant component of the global climate system warming (Roemmich et al., 2015. Argo data are processed by national Data Assembly Centers (DACs) and converted to the Argo standard format before being transmitted to the GDACs (Carval et al. 2008) and the World Meteorological Organization Global Telecommunication System. There are two stages of quality control for Argo data: real time (R) and delayed mode (D)
