2.3. Interaction of EMR with the Atmosphere

Try these first

1. 1.

   What kind of scattering makes the sky appear blue?

   Hint

   Think about which wavelength is affected the most.

2. 2.

   What is Mie Scattering?

   Hint

   Consider what types of particles influence longer wavelengths.

3. 3.

   What type of scattering is responsible for the blue color of the sky?

   • A. Mie Scattering
   • B. Rayleigh Scattering
   • C. Non-selective Scattering

   Hint

   Remember which scattering relates to shorter wavelengths.

4. 4.

   True or False: Atmospheric absorption can lead to certain wavelengths being unusable for remote sensing.

   • True
   • False

   Hint

   Reflect on the interactions between gases and EMR.

5. 5.

   How would you design a remote sensing mission considering atmospheric scattering and absorption? Discuss the criteria for choosing wavelengths.

   Hint

   Think about the relationship between wavelength size and scattering impact.

6. 6.

   Given a scenario where the atmosphere has high humidity, how will this affect the choice of wavelengths for your remote sensing data collection?

   Hint

   Consider how absorption influences usable wavelengths.
