Oceansat is a series of Earth observation satellites built, launched, and operated by Indian Space Research Organisation, and dedicated to oceanography and atmospheric studies.
Oceansat satellites facilitate a range of applications including documenting chlorophyll concentration, phytoplankton blooms, atmospheric aerosols and particulate matter[1] as well as marine weather forecast to predict cyclones.
The satellite carried an Ocean Colour Monitor (OCM) and a multi-frequency scanning microwave radiometer.
Oceansat-2 is designed to provide service continuity for operational users of the Ocean Colour Monitor (OCM) instrument on Oceansat-1 and enhance the potential of applications in other areas.
[11] Oceansat-3 was launched on 26 November 2022,[12] Oceansat-3 will provide continuity to operators of OCM and enhanced ability in other applications by way of simultaneous Sea Surface Temperature (SST) measurements.
