MODIS/Terra BRDF/Albedo Parameters 16-Day L3 Global 0.05Deg CMG V004Entry ID: MOD43C24
Abstract: Decommissioned product.
The 16-day, 0.05 degree global BRDF/Albedo parameter product (MOD43C2) is a level-3 Climate Modeling Grid delivering the model parameters used to create the MODIS Global Albedo product (MOD43C1). The MOD43C2 product is produced on a flat latitude/longitude grid in HDF-EOS format. Three BRDF model parameter values are given for each of 10 wavelength bands (7 MODIS Land ... Bands, 459-2155 nm, in addition to three broad bands compiled from the 300-700 nm, 700-5000 nm, and 300-5000 nm wavelengths). These three weighting parameters (fiso , fvol , fgeo) are associated with the Ross-Thick/Li-Sparse Reciprocal BRDF semi-empirical model, which best describes the scattering (anisotropy of each) pixel. The data are stored band interleaved by pixel. Extensive quality information (in a bit-packed format) is also provided (3600x7200x10 row/column/band).
The global measures of albedo are derived averages computed from the 16-day 1-km global albedo product. The 1-km global albedo, computed by integrating the Bi-directional Reflectance Distribution Function (BRDF), describes the characteristic anisotropy of the land surface. The MODIS BRDF parameters are the best fit model weights determined by inverting the multi-date,
multi-angular, cloud-free, atmospherically corrected surface reflectance observations acquired by MODIS over a 16-day period. These parameters can be used in a forward version of the model to fully reconstruct the surface BRDF and thus correct directional reflectances to a common view geometry or to compute the integrated black-sky (at any desired solar zenith angle) and white-sky albedos (as with MOD43C1). Alternately, the parameters can be used directly with a simple polynomial to easily estimate the black-sky albedo with good accuracy for any desired solar zenith angle.
