When we consider the fact that nearly three-quarters of the surface of the globe is covered by oceanic water, we begin to realise that the molecular scattering of light in liquids may possess an astronomical significance, in fact contribute in an important degree to the observed albedo of the earth.
2003–2004 mean annual clear-sky and total-sky albedo Earth's surface albedo is regularly estimated via Earth observation satellite sensors such as NASA 's MODIS instruments on board the Terra and Aqua satellites.

Also, the geometric albedo of Chiron's rings as determined by spectroscopy is consistent with that used to explain Chiron's long-term brightness variations.
A layer of snowfall increases local albedo, reflecting away sunlight, leading to local cooling.
Albedo–temperature feedback When an area's albedo changes due to snowfall, a snow–temperature feedback results.
