| 21. | Landsberg discovered the fine structure in Rayleigh scattering.
|
| 22. | This happens because of Rayleigh scattering, the same property that causes the sky to appear blue.
|
| 23. | It is first corrected for Rayleigh scattering and then subtracted from the Rayleigh corrected band 1.
|
| 24. | When illumination is indirect, Rayleigh scattering in the upper atmosphere will lead blue wavelengths to dominate.
|
| 25. | The statement that the sky is blue needs explaining that it is due to Rayleigh scattering.
|
| 26. | This is described by Rayleigh scattering, an effect that creates Earth's blue sky and red sunsets.
|
| 27. | Rayleigh scattering is much greater for blue light than for other colours due to its shorter wavelength.
|
| 28. | The blue of glacier ice is sometimes misattributed to Rayleigh scattering due to bubbles in the ice.
|
| 29. | The Sun is in fact white, but appears yellow through Earth's atmosphere due to atmospheric Rayleigh scattering.
|
| 30. | But when the sun is above the horizon anywhere, Rayleigh scattering makes the whole sky pretty bright.
