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.
