A combination of Bands 1, 4, 3 displays an R, G, B Nadir BRDF-Adjusted Reflectance image using data acquired between January 17 and February 1, 2007 over the Adriatic Sea, including Italy, Croatia, Bosnia, Serbia, and Albania (h19v04). Black pixels are either clouds (top) or water bodies (bottom). White pixels represent snow, as determined using BRDF/Albedo Quality

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.
Version-5 MODIS/Terra+Aqua BRDF/Albedo products are Validated Stage 1, meaning that accuracy has been estimated using a small number of independent measurements obtained from selected locations and time periods and ground-truth/field program efforts. Although there may be later improved versions, these data are ready for use in scientific publications.
