The intensity of albedo temperature effects depends on the amount of albedo and the level of local insolation (solar irradiance); high albedo areas in the Arctic and Antarctic regions are cold due to low insolation, whereas areas such as the Sahara Desert, which also have a relatively high albedo, will be hotter due to high insolation.
Cloud albedo is a measure of the albedo or reflectivity of a cloud. Clouds regulate the amount of solar radiation absorbed by a planet and its solar surface irradiance . Generally, increased cloud cover correlates to a higher albedo and a lower absorption of solar energy .
Limited application of reflective surfaces can mitigate urban heat island effect. [3] Reflective surfaces can be used to change the albedo of agricultural and urban areas, noting that a 0.04-0.1 albedo change in urban and agricultural areas could potentially reduce global temperatures for overshooting 1.0 °C.

Ice–albedo feedback is a climate change feedback, where a change in the area of ice caps, glaciers, and sea ice alters the albedo and surface temperature of a planet. Because ice is very reflective, it reflects far more solar energy back to space than open water or any other land cover. [1] It occurs on Earth, and can also occur on exoplanets ...
Details of how clouds interact with shortwave and longwave radiation at different atmospheric heights [17]. Clouds have two major effects on the Earth's energy budget: they reflect shortwave radiation from sunlight back to space due to their high albedo, but the water vapor contained inside them also absorbs and re-emits the longwave radiation sent out by the Earth's surface as it is heated by ...

The presence of extensive, year-around sea ice, which has a high albedo (reflectivity), adds to the albedo of the ice sheets' own bright, white surface. [19] Antarctica's coldness means it is the only place on Earth where an atmospheric temperature inversion occurs every winter; [ 19 ] elsewhere on Earth, the atmosphere is at its warmest near ...
