This Version 4 product has been decommissioned.
The MODerate-resolution Imaging Spectroradiometer (MODIS) BRDF/Albedo Model Parameters product (MCD43B1) contains three-dimensional (3D) data sets providing users with weighting parameters for the models used to derive the Albedo and BRDF products (MCD43B3 and MCD43B4). The models support the spatial relationship and parameter characterization best ... describing the differences in radiation due to scattering (anisotropy) of each pixel, relying on multi-date, atmospherically corrected, and cloud-cleared input data measured over 16-day periods.
The BRDF/Albedo Model Parameters can be used with a simple polynomial to easily estimate the black-sky albedo with good accuracy for any desired solar zenith angle. BRDF shape and properties are further described by the shape indicators included in the product.
Both Terra and Aqua data are used in the generation of this product, providing the highest probability for quality input data.
