This version four product has been decommissioned.
The MODerate-resolution Imaging Spectroradiometer (MODIS) Nadir BRDF Adjusted Reflectance (NBAR) product MCD43B4 provides 1-kilometer reflectance data adjusted using the bidirectional reflectance distribution function (BRDF) of MCD43B1 to model values as if they were acquired from a nadir view. MCD43B4 reflectance represents that best ... characterization of the surface possible from the inputs available over a 16-day period. If observations at view and illumination angles other than nadir are required then the MCD43B1 models should be used directly in the BRDF Forward Model. The MCD43B4 NBAR quantities are provided as a level-3 gridded product in the Sinusoidal projection.
Both Terra and Aqua data are used in the generation of this product, providing the highest probability for quality input data and designating it as an "MCD," meaning "Combined," product.
