Category:Atmospheric optical phenomena of Earth
This category and its sub-cats are intended for images of all atmospheric optical phenomena, ie phenomena of optical nature happening within Earth's atmosphere.
These phenomena can involve several types of physical processes:
- light rays and shadows projecting on air, sometimes in association with light scattering (shadows of clouds or contrails, of mountains, Earth's shadow and the Belt of Venus; opposition effects; Crepuscular rays; Brocken spectres);
- Refraction in layers of air (looming, mirages, Green flash);
- Refraction in water drops (rainbows) or ice crystals (haloes);
- Diffraction around small particles (coronae, glories);
- extra-atmospheric agents interfering with the atmosphere: the aurora is not strictly speaking Atmospheric Optics, as it involves particles coming from space. However, it is traditionally considered a branch of At Optics, as well as the airglow. Aurorae are known to happen on other planets of the Solar system.
If you are not sure of the phenomenon involved and/or relevant sub-cat, please upload the media to this root category.
