INCOIS is an autonomous organization of the Government of India, under the Ministry of Earth Sciences (MoES) and a unit of the Earth System Science Organization (ESSO) established in 1999. MoES had initiated the project as "PFZ Mission" handed over the National Remote Sensing Centre (NRSC). And the project is came into wide area, it is separated from the NRSC and named as new organization called Indian National Centre for Ocean Information Services under by scientist Dr. A.Narendra Nath. Apart from this, the organization also had services in Indian Early Tsunami Warning, Ocean State Forecast, Tsunami early warnings, Strorm surge warnings, Coarl bleaching alerts, Updates of climate indices, Ocean Modeling, Data and Web Services Management. By this INCOIS was identified as one of the key International Oceanic Organizations. It also give information services on Potential Fishing Zone (PFZ) Advisory, Tuna Fishery Advisory. 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. It also provides the information on physical, chemical, biological and geological parameters of ocean and coasts. This organization information is supported by the data received from Ocean Observing Systems in the Indian Ocean (both the in-situ platforms and satellites) as well as by a chain of Marine Data Centres. INCOIS has been designated as the National Oceanographic Data Centre by the International Oceanographic Data Exchange Programme (IODE) of International Oceanographic Commission (IOC). Further, INCOIS serves as the National Argo Data Centre, Regional Argo Data Centre, and also the regional data centre and clearing house for the Indian Ocean region for the IOGOOS Programme. Now INCOIS provides forecast of 1. Height, direction and period (of both wind waves and swell waves). 2. Sea surface currents. 3. Sea surface temperature. 4. Mixed Layer Depth (the well mixed upper layer of the sea). 5. Depth of the 20 degree isotherm ( a measure of the depth of the thermocline). 6. Astronomical tides. 7. Wind speed and direction. 8. Oil-spill trajectory The forecast is available separately on different oceans. Further, it provides more detailed forecast information for specific locations like fish landing centres, small fishing harbours, commerical ports, etc. as well as for the coastal waters of the maritime states, union territories and island regions of India. The forecasts are generated by a suite of state-of-the art numerical models, which are customized to simulate and predict the Indian Ocean features accurately. The models used are I) WAVEWATCH III, MIKE and Regional Ocean Modeling System (ROMS) and General NOAA Oil Modeling Environment (GNOME). Atmospheric forecast products from different meteorological forecasting agencies (NCMRWF and ECMWF) are used for forcing these models in the forecast mode.
