Roles of INCOIS as Data Centre INCOIS, is the central repository for marine data in the
country. Receives voluminous oceanographic data in real time, from
a variety of in-situ and remote sensing observing systems. The Ocean Information Bank provides information on Physical, chemical Biological and Geological parameters
The Ocean Information Bank is supported by the datareceived from Ocean Observing Systems in the IndianOcean (both the in-situ platforms and satellites). INCOIS has been designated as the National
Oceanographic Data Centre (NODC) by the IODE/IOC. INCOIS serves as the National Argo Data Centre, Regional

Quality Control Procedures Every data is passed through prescribed Quality
Control procedures. At INCOIS two types of QC procedures are followed.
They are: Real Time Quality Control. Delayed Mode Quality control.
Apart from these OA based QC, Visual QC, Clusterbased QC and Polygon based QC is followed. GUI are developed for performing these QC
procedures.

Argo data base INCOIS Argo program started in 2002 and till now 396
floats are deployed. Total 133 floats are active. In total ~800 floats are active in the Indian Ocean. A total of ~2,50,000 temperature and salinty profile are
archived at INCOIS. All these are passed through RT and DM quality
control procedures. Valued added products are generated after that using
OA and Variational Analysis procedures.
