When seen from a distance, the ocean surface has a low albedo, as do most forests, whereas desert areas have some of the highest albedos among landforms. Most land areas are in an albedo range of 0.1 to 0.4. [14] The average albedo of Earth is about 0.3. [15] This is far higher than for the ocean primarily because of the contribution of clouds.
The Kuiper quadrangle, located in a heavily cratered region of Mercury, includes the young, 55-km-diameter crater Kuiper (11° S., 31.5° ), which has the highest albedo recorded on the planet, [1] and the small crater Hun Kal (0.6° S., 20.0° ), which is the principal reference point for Mercurian longitude (Davies and Batson, 1975).
In planetary geology, an albedo feature is a large area on the surface of a planet (or other Solar System body) which shows a contrast in brightness or darkness with adjacent areas. Historically, albedo features were the first (and usually only) features to be seen and named on Mars and Mercury .
A map of Mercury [1] made in the 1910s by astronomer Eugène Michel Antoniadi shows the following albedo features, localized by a grid in which 0° longitude is the (assumed) subsolar meridian. No certain connection has been made between these features and the topographic features viewed on Mercury by the Mariner 10 spacecraft. Mariner 10 ...
The volcano's location corresponds to the classical albedo feature Ascraeus Lacus.. Ascraeus Mons was discovered by the Mariner 9 spacecraft in 1971. The volcano was originally called North Spot [2] because it was the northernmost of only four spots visible on the surface due to a global dust storm that was then enshrouding the planet.
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 .
As of 2023, it has the highest-known albedo of any planet. [1] Characteristics. LTT 9779 b is one of the few known planets in the Neptunian desert. [2]
Ice–albedo feedback also has a smaller, but still notable effect on the global temperatures. Arctic sea ice decline between 1979 and 2011 is estimated to have been responsible for 0.21 watts per square meter (W/m 2 ) of radiative forcing , which is equivalent to a quarter of radiative forcing from CO 2 [ 13 ] increases over the same period.
