Consider the following statements: The satellite Oceansat-2 launched by India helps in1. 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?
✓ Correct answer: d) 1,2 and 3
ExplanationOceansat-2, launched by ISRO in 2009, is an Earth observation satellite designed to study oceanic and atmospheric conditions.It supports applications like ocean forecasting, fishing zone mapping, and monitoring coastal and atmospheric parameters.Statement 1 is correct: Oceansat-2 is equipped with sensors such as the Scatterometer and Ocean Color Monitor (OCM), which help assess atmospheric parameters like water vapour content.Statement 2 is correct: By measuring sea surface winds and temperatures, the satellite is capable of understanding and predicting monsoon dynamics, which are closely tied to oceanic and atmospheric interactions.Statement 3 is correct: The Ocean Color Monitor onboard can detect chlorophyll concentrations, sediment levels, and other indicators of water quality, helping monitor and assess pollution in coastal regions effectively.124
