Description

The MCD43A1 V6.1 Bidirectional Reflectance Distribution Function and Albedo (BRDF/Albedo) Model Parameters dataset is a 500 meter daily 16-day product. The Julian date represents the 9th day of the 16-day retrieval period, and consequently the observations are weighted to estimate the BRDF/Albedo for that day. The MCD43A1 algorithm, as is with all combined products, chooses the best representative pixel from a pool that includes all the acquisitions from both the Terra and Aqua sensors from the retrieval period.

The MCD43A1 provides the three model weighting parameters (isotropic, volumetric, and geometric) for each of the MODIS bands 1 through 7 and the visible (vis), near infrared (nir), and shortwave bands used to derive the Albedo and BRDF products (MCD43A3 and MCD43A4). The Mandatory Quality layers for each of the 10 bands are supplied as well.
