MODIS Terra and Aqua BRDF Albedo Nadir BRDF-Adjusted Reflectance Daily L3 Global 500m 2007

The MODIS Terra and Aqua MCD43A4 Version 6.1 product provides Nadir Bidirectional Reflectance Distribution Function (BRDF)-Adjusted Reflectance (NBAR) at 500 m spatial resolution. The dataset is generated daily using 16 days of combined Terra and Aqua MODIS observations. Directional reflectance values are adjusted to remove view angle effects, resulting in a stable and consistent NBAR product. The data are temporally weighted to the ninth day of the 16-day period, which is reflected in the Julian date of the file name. The product includes NBAR reflectance for MODIS bands 1-7 along with simplified mandatory quality layers. For detailed quality information, users are advised to consult the corresponding MCD43A2 dataset.
