[L. whiteness]

albedo

/al·be·do/ (al-be´do) [L.] whiteness.

albedo

[albē′dō] pl. albedos
Etymology: L, albus, white
a whiteness, as a surface reflection.

albedo

the reflectivity of a surface usually expressed as the percentage of radiation reflected e.g. solar radiation reflected from the atmosphere, clouds and the earth's surface. The albedo of an object gives an indication of its composition.

Our results describing the influence of albedo on surface conditions are shown in Fig.
Besides albedo, the values of the diffuse attenuation coefficient of ice ([K.
As already mentioned, the values of T do not allow us to separate the influence of albedo from the influence of other ice properties.
According to our measurements, the albedo of ice in sub-polar regions can vary widely (0.
East Antarctic sea ice: albedo, thickness distribution and snow cover.
By suspending instruments on a 50-meter-long cable across each test plot, the researchers could measure the albedo of the terrain during winter and spring without disturbing the plots' vegetation or the surface of the snow as it melted.
At sites where grasses and short, supple shrubs were prevalent, the vegetation was bent to the ground with the weight of the overlying snow, and the albedo was about 85 percent.
The type of vegetation at a site greatly affected not only overall albedo but also how quickly albedo changed during the snowmelt.
MELTING CAP A transition taking place in the ice-covered ocean that sits atop the world may prove far more significant for the Arctic's albedo than is the shrub expansion on land.
So, when ice melts and albedo takes a nosedive, the upper layers of the ocean absorb more sunlight, and sea-surface temperatures rise.
