®3.2.5.1 Scattering
- Rayleigh:
-
- Particles very small compared t wavelength
- Shorter wavelengths scattered more than longer
-Why sky is blue
- Dominat scattering in upper atmosphere
- Mie
-
- Particles about the same size as the wavelength
- Sunset (long path length)
- Rayleigh scatters blue light out of path
- Mie scatters the remaining yellow and red into the
surrounding skies
- Mostly in lower part of atmosphere
- Non-selective
-
- Particles much longer than the wavelength
- All wavelengths scattered equally
-Why fog and clouds appear while
