The reflecting power of a surface, expressed as a ratio of reflected radiation to incident or incoming radiation; it is sometimes expressed as a percentage. Albedo is also called the "reflection coefficient" and derives from the Latin...

The portion of the solar radiation reaching the earth’s surface which is reflected immediately back into the atmosphere. The average value is about 40% but varies locally with the nature of the surface on which the radiation impinges, see Solar...

The albedo of an object is the extent to which it diffusely reflects light, defined as the ratio of diffusely reflected to incident electromagnetic radiation. It is a unitless measure indicative of a surface's or body's diffuse reflectivity. The word is...

ABSTRACT A coarse resolution coupled ocean-atmosphere simulation in which surface albedo feedback is suppressed by prescribing surface albedo, is compared to one where snow and sea ice anomalies are allowed to affect surface albedo. Canonical CO^sub 2^-doubling experiments were performed with both models...

ABSTRACT The strength of snow-albedo feedback (SAF) in transient climate change simulations of the Fourth Assessment of the Intergovernmental Panel on Climate Change is generally determined by the surface-albedo decrease associated with a loss of snow cover rather than the reduction in snow...

Earlier blooms. Less snow to shovel. Unseasonable warm spells. Signs that winters in the Northeast are losing their bite have been abundant in recent years and now researchers have nailed down numbers to show just how big the changes have been.A study of weather station...
