An observational network array of about 3000 autonomous profiling floats, known as Argo, has been evolving since the year 2000. India is a participant of the International
Argo program, and Indian National Centre for Ocean Information Services(INCOIS) has the overall responsibility for implementation of the Indian Argo project, including the Argo regional centre (ARC) for the Indian ocean. One of
the prime responsibility of regional data centre is delayed mode duality control (DMQC). The Argo array is delivering large number vertical profiles of temperature,salinity and other parameters from the surface to depths up to 2000 m. While floats are expected to give good measurements of temperature and pressure, salinity measurements sometimes show significant sensor drift with time or offsetsThe calibration procedure is called WJO method in short and OW method, after the recent modification by Owens and Wong [2009]. This report presents the major components of the work carried out at INCOIS using the WJO/OW software to provide best quality data to the end user. This report also presents all floats calibrated at INCOIS and their WJO/OW recommended corrections and the final decision taken
about each floats considering the regional oceanography and various other factors (in attached CD-ROM)
