Question

Consider the following statements: The satellite Oceansat-2 launched by India helps in 1. estimating the water vapour content in the atmosphere. 2. predicting the onset of monsoons. 3. monitoring the pollution of coastal waters. Which of the statements given above is/are correct?

Accepted Answer

The correct answer is D because Oceansat-2, launched by ISRO in 2009, was designed for oceanographic and atmospheric studies using three main instruments.

First, the Ocean Colour Monitor OCM-2 helps in monitoring coastal water quality and pollution by tracking suspended sediments and chlorophyll concentrations.

Second, the Scanning Scatterometer OSCAT measures ocean surface wind speed and direction, which is critical for predicting the onset of monsoons and identifying cyclones.

Third, the Radio Occultation Sounder for Atmosphere ROSA is specifically used to derive vertical profiles of humidity and temperature, which helps in estimating the water vapour content in the atmosphere.

Since the satellite addresses all three areas mentioned, all statements are correct.
