    MODIS/Terra+Aqua BRDF/Albedo Quality Daily L3 Global 500 m SIN Grid

    Metadata Updated: February 22, 2025

    The MODIS Near Real Time (NRT) Combined Aqua and Terra Bidirectional Reflectance Distribution Function and Albedo (BRDF/Albedo) Quality, MCD43A2N is a L3 daily 16-day composite global gridded tiled product that provides full set of quality control flags for use in determining the quality of the retrievals at pixel level in the daily L3 BRDF/Albedo suite of products: BRDF/Albedo Model Parameters (MCD43A1N), Albedo (MCD43A3N) and the NBAR (MCD43A4N).

    There is a significant change in the science algorithm of the Collection 61 (C61) NRT BRDF/Albedo products and, therefore significant differences/discontinuities between the C6 and C61 products. C61 algorithm changes are intended to minimize the differences between the NRT and Standard BRDF. The C61 NRT BRDF code has been modified to allow for an extra round of magnitude inversion, following a full inversion using the full set of inputs. This extra magnitude inversion will only use the set of 9 days that are overlapping between standard and NRT, with the highest weight being assigned to the last day.
