Albedo is an important concept in climate science ... very low albedo in spite of its high reflectivity at high angles of incident light. ... that the global mean ...
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 ...
A European Space Agency satellite has observed the shiniest exoplanet ever discovered. The scorching world has reflective clouds made of silicates and titanium.
[25] [26] Volcanic ashes with a high silica content, known as felsic ashes, stand out from the background sediments due to their high albedo and reflectance values. [10] In contrast, mafic ashes, which have low silica content, exhibit lower reflectance due to their purity compared to the mixed compositions of the background sediments. [24]
The optical properties of matter are studied in optical physics (a subfield of optics) and applied in materials science. The optical properties of matter include: Refractive index; Dispersion; Transmittance and Transmission coefficient; Absorption; Scattering; Turbidity; Reflectance and Reflectivity (reflection coefficient) Albedo; Perceived ...
