- same data format (netCDF - OceanSites 1.2)
- same data flagging convention
- same ftp structure
- same file naming convention
Same data format
For each region, the In Situ Distribution Unit distributes all its data and metadata products in NetCDF files on an FTP server.
The data files format is an implementation of NetCDF OceanSITES format.

NRT quality controls are available here
Quality control flag scale:| Code | Meaning | Comment |
|---|---|---|
| 0 | No QC performed | - |
| 1 | Good data | All real-time QC tests passed |
| 2 | Probably good data | - |
| 3 | Bad data that are potentially correctable | These data are not to be used without scientific correction |
flagging convention
| Code | Meaning | Comment |
|---|---|---|
| 4 | Bad data | Data have failed one or more of the tests |
| 5 | Value changed | Data may be recovered after transmission error |
| 6 | Not used | - |
| 7 | Nominal value | Data were not observed but reported.Example: an instrument target depth |
| 8 | Interpolated value | Missing data may be interpolated from neighbouring data in space or time |
| 9 | Missing value | The value is missing, is not reported, is not applicable |
same ftp structure
Each DU distributes all its data and metadata products in NetCDF files on an FTP server sticking with the same structure:
