The ratio of the amount of radiation reflected from an object's surface compared to the amount that strikes it. This varies according to the texture, color, and expanse of the object's surface and is reported in percentage. Surfaces with high albedo include sand and snow, while low albedo rates include forests and freshly turned earth.
|Fresh Snow||80 to 90%|
|Deciduous Trees||15 to 18%|
|Conifer Forest||8 to 15%|
The Earth′s albedo varies mainly through varying cloudiness, snow, ice, leaf area, and land cover changes.
