The MODerate-resolution Imaging Spectroradiometer (MODIS) Reflectance product MCD43A4 provides 500-meter reflectance data adjusted using a bidirectional reflectance distribution function (BRDF) to model the values as if they were taken from nadir view. The MCD43A4 product contains 16 days of data provided in a level-3 gridded data set in 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.
Version-5 MODIS BRDF & Albedo products have attained Validation Stage 3.
