Spectral and Broadband Albedo of Antarctic Sea-ice Types
Listed in NASA Earthdata CMR
The albedo, or reflection coefficient, is a measure of the diffuse reflectivity of an irradiated surface.
Description
With the sunlit atmosphere as a light source, and sea-ice as a diffuse reflecting surface, the albedo would be the fraction of incident light that is returned to the atmosphere. A perfect (white) reflecting surface would have an albedo of 1; a perfect (black) absorbing surface would have an albedo of 0.
The albedo of sea-ice is needed to assess the solar energy budget of the marginal ice zone, to compute the partial solar bands in radiation budgets in general circulation and earth system models, and is also needed to interpret remote sensing imagery data products.
