Q: Contrast Rayleigh scattering vs. Mie scattering.
Rayleigh scattering is generally caused by smaller particles in the atmosphere (eg atmospheric gases) while Mie scattering is caused by somewhat larger particles such as dust. Also, Rayleigh scattering happens high in the atmosphere while Mie scattering happens lower in the atmosphere, and Rayleigh scattering happens to wavelengths of light significantly larger than the scattering particles while Mie scattering happens to wavelengths of light around the same size as the scattering particles.

Correct!

Q: What is the benefit from having the A-train satellites follow the same path to one another in quick succession?

Allowing the A-train satellites to follow the same path in quick succession allows the satellites to gather data and images almost simultaneously. This lets us analyze all factors at one given time so we can make connections instead of the data being given at sporadic time intervals, which isn't much use alone (happens if the satellites were in different paths or weren't taken very close to the same time).

Restarting this.

What is Radiative Forcing?
The biologist speculates, "What's the meaning of life?"
The physicist asks, "In the universe, does matter really matter?"
The chemist replies, "I shall find solutions to both questions."

Relative effectiveness of a GHG to restrict long-wave radiation from escaping back into space. Negative radiative forcing means cooling, positive means net heating.

Also can someone teach me how to use the answer thing?

I guess I'll restart this question marathon.

A higher spatial resolution leads to a smaller IFOV, which reduces radiometric resolution, so they have an inverse relationship.
