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. NCEI also implements reanalysis updates and corrections provided by the U.S. Global Ocean Data Assimilation Experiment (GODAE) and French Institute for Research and Exploration of the Sea (IFREMER) Global Data Assembly Centers (GDACs), which provide access to real-time and near real-time data and perform initial quality control measures.
Individual profiles organized by ocean and subdivided into years and months. Each month has an inventory table that includes path and the file names, monthly station observations, sampling date (year, month, and day), and location (latitude and longitude, negative numbers are for southern latitudes and western longitudes).
Profiles, metadata, and technical information files grouped by the Argo float identification numbers. Consult the Grey Floats table for a list of floats with documented or potential technical issues.
Data Assembly Centers Inventory
Real time, quality controlled float data from each Argo Data Assembly Center (DAC).

More About Argo
- always nodc, to indicate NODC format
- a seven-digit number beginning with A9xxxx. A is the World Meteorological Organization deployment region, 9 is a float indicator, and xxxx is a number allocated serially.
- three or four-character string indicating the file's data type.
- Vertical distribution of measured parameters such as temperature, salinity, and conductivity of profiling floats
- Inventory tables for each float on the disk
- Status of each float as of CD production
- Vertical distribution of measured parameters in the so called "one-file per float" or "multi-profile" formats
- filename extension, indicating the kind of data stored in the file. e.g., nc = netCDF
- always nodc
- data mode of the float, R for real-time and D for delayed-mode
- a seven-digit number, A9xxxxx as described above
- a three-digit number indicating the cycle number of the float
- always nc to indicate netCDF format
