Near nadir imagers do not provide the multiangle observations necessary to capture the multiangle reflective character described by the surface BRDF Therefore the Landsat albedo algorithm couples atmospherically corrected 30m Landsat . source sensor surface element normal brPage 3br BRDF Bidirectional Reflectance Distribution Function T I source viewing direction surface element normal incident direction I T I T surface I T surface I T Irradiance at Surface in direction I T Radian All Rights Reserved Introduction Albedo is Latin meaning whiteness The albedo of a surface is the fraction of the incident sunlight that the surface re64258ects Radiation that is not re64258ected is absorbed by the surface The absorbed energy raises ?.
