ISRO said the three payloads on-board Oceansat-2 — ocean colour monitor (OCM), scatterometer and radio occultation sounder (ROS) for atmospheric studies — have been successfully turned on.

The OCM, a multi-spectral imaging radiometer, provides information on chlorophyll concentration and helps locate potential fisheries zones. The scatterometer, an active microwave sensor, facilitates retrieval of sea-surface wind speed and direction, and monitoring polar sea-ice. The ROS measures parameters pertaining to lower atmosphere and ionosphere.

The data provided by the different sensors on-board Oceansat -2, will also facilitate monitoring of turbidity and suspended sediments, sea-state and sea-surface winds, and meteorological/climatological studies. The satellite collects data over the entire globe once in two days.
