For the measurement/estimation of which of the following are satellite images and remote sensing data is used?

  1. 1.Chlorophyll content in the vegetation of a specific location.
  2. 2.Greenhouse gas emission from rice paddies of a specific location.
  3. 3.Land surface temperature of a specific location.

Select the correct answer using the code given below:

  1. A.1 only
  2. B.2 and 3 only
  3. C.3 only
  4. D.1, 2 and 3
▶ Answer & Explanation

Correct answer: D. 1, 2 and 3

Satellite remote sensing is a versatile tool capable of monitoring various environmental parameters. It can measure chlorophyll content in vegetation, which is crucial for assessing plant health and photosynthetic activity. Additionally, it can estimate greenhouse gas emissions from agricultural lands like rice paddies, and monitor land surface temperature over large areas, providing insights into climate and land use patterns.
