5.8. Interaction of EMR with Atmosphere

Try these first

1. 1.

   What are the four interactions of EMR with materials?

   Hint

   Think of the acronym STAR.

2. 2.

   What is Rayleigh scattering?

   Hint

   Remember the blue sky example.

3. 3.

   Which interaction results in the color of the sky appearing blue?

   • Rayleigh Scattering
   • Reflection
   • Absorption

   Hint

   Remember the scattering process.

4. 4.

   True or False: Absorption leads to an increase in detected EMR.

   • True
   • False

   Hint

   Think about how colors absorb light.

5. 5.

   Consider a scenario where remote sensing data has a lot of atmospheric interference. Discuss how you would approach correcting the images.

   Hint

   Recall specific methods used in remote sensing.

6. 6.

   If you were to design a sensor for remote sensing, what features would you consider to minimize the impacts of scattering?

   Hint

   Think about different wavelengths of EMR.
