The project envisages development of algorithms and models for retrieval of met-ocean parameters i.e. Surface Temperature (SST), Winds, Waves, Bathymetry, suspended matter, mixed layer depth, chlorophyll, aerosol, water vapour, clouds, currents and sea level from satellite sensors. The data assimilation models on waves and ocean circulation would also be developed. The algorithms would be developed in two phases. In Phase I packaging of software for retrieval of parameters such as waves, winds, SST, mixed layer bathymetry and heat flux is being carried out whereas under Phase II retrieval algorithms for parameters i.e. Chlorophyll, Antarctic snow, aerosols, water content, sea level, rainfall and currents will be developed. The algorithms being developed in Phase I&II would be fine-tuned and converted into software packages for operational use in the Ocean Information Service (OIS). R&D activities are continued for up-gradation of existing algorithms and initiation of the development of software by using other algorithms and improved models. During the year development of retrieval algorithms and validation of Sea Surface Temperature and waves from ERS-1 was completed which includes customization of the software. Studies on latent heat flux and eddies would be completed from ERS and Altimeter, respectively. Development of software for estimation of coastal bathymetry from SAR and Altimeters was completed.
