Reflectance and albedo

Web8. nov 2016 · So, you could have very high reflectance of low energy "light" - maybe even near 100 % which would be a 1. But since the light striking the surface and reflecting is low energy, the "number" that represents the energy will also be lower. Albedo seems to be the reflective property of an object - it could be applied to planets, or landcover. http://www.differencebetween.net/science/difference-between-albedo-and-reflectance/

This is a measurement of how well a surface, such as snow or ice, bounces sunlight back into space ... WebThe microstructure of the uppermost portions of a melting Arctic sea ice cover has a disproportionately large influence on how incident sunlight is reflected and absorbed in the ice/ocean system. The surface scattering layer (SSL) effectively backscatters solar radiation and keeps the surface albedo of melting ice relatively high compared to ice with the SSL … moveit shipment tracking https://bulkfoodinvesting.com
