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

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

Select the correct answer using the code given below.

Satellite images and remote sensing data have various applications:

Statement 1: Multi-spectral images from thematic mappers can be used to assess the health of vegetation, including determining the chlorophyll content of plants in specific locations. This is done by analyzing reflected electromagnetic radiation at different wavelengths.

Statement 2: Radiometers and photometers can detect the emission spectra of various chemicals in the atmosphere, providing data on chemical concentrations. This includes greenhouse gas emissions from sources like rice paddies.

Statement 3: It is possible to measure land surface temperatures using remote sensing data.

Therefore, all three statements are correct.

Hence, option D is the correct answer.
