MODIS Bidirectional Reflectance Distribution Function (BRDF) / Albedo Parameter
Overview
The Bidirectional Reflectance Distribution Function (BRDF)/Albedo parameters provide:
• coefficients for mathematical functions that describe the BRDF of each pixel in the seven MODIS 'Land' bands (1- 7); and
• albedo measurements derived simultaneously from the BRDF for bands 1-7 as well as three broad bands (0.4-0.7, 0.7-3.0, and 0.4- 3.0 micrometers).
The models support the spatial relationship and parameter characterization best describing the differences in radiation due to the scattering (anisotropy) of each pixel, relying on multi-date, atmospherically corrected, cloud-cleared input data measured over 16-day periods. Both Terra and Aqua data are used in the generation of this product, providing the highest probability for quality input data.
