MODIS/Terra+Aqua Nadir BRDF-Adjusted Reflectance 16-Day L3 0.05 Degree CMG V004Entry ID: MCD43C14
Abstract: Decommisioned product.
The 16-day 0.05Deg global albedo product (MCD43C1) is a Level-3 Climate Modeling Grid product that provides measures of Earth's white-sky and black-sky albedo. These measures are derived averages computed from the 16-Day 1 km global albedo product (MCD43B3). The 1 km global albedo is computed by integrating the Bi-directional Reflectance Distribution Function (BRDF), which ... describes the characteristic anisotropy of the land surface. The MODIS BRDF parameters are modeled by inverting multi-date, multi-angular, cloud-free, atmospherically corrected surface reflectance observations acquired by MODIS over a 16-day period.
Black-sky albedo and white-sky albedo mark the extreme cases of both completely direct and diffuse illumination. Black-sky albedo, or directional hemispherical reflectance, is defined as albedo in the absence of a diffuse component and is a measure of a surface's relative brightness when illuminated from a certain angle. MODIS black-sky albedo is calculated at the solar zenith angle of local solar noon. White-sky albedo, or bi-hemispherical reflectance, is defined as albedo in the absence of a direct component when the diffuse component is isotropic.
MCD products are generated using a combination of Terra and Aqua acquisitions to optimize data quality.
NOTE: These products are validated, meaning that product uncertainties are well defined over a range of representative conditions. Although there may be later improved versions, these data are ready for use in scientific publications.
