Abstract:
This product has been decommissioned. MOD43B1 contains four dimensional data sets of BRDF and Albedo parameters: x,y, and parameter values are stored for each wavelength band of data. For example, a cell may reflect the use of all 7 MODIS Land Bands (459-2155 nm) in addition to 3 broad bands compiled from 300-700 nm, 700-5000 nm, and 300-5000 nm. This 4D combination provides users with spatial orientation as well as the weighting parameters associated with the models best describing the differences in radiation due to scattering (anisotropy) of each pixel. MODLAND's Level-3 BRDF/Albedo products (MOD43Bs) are provided globally as discrete 1200 by 1200 element tiles in a Sinusoidal Grid projection in a HDF-EOS format. MOD43B1 provides the BRDF model parameters, MOD43B3 provides the black-sky albedo (at a solar zenith angle of 45 degrees) and the white-sky albedo, and MOD43B4 provides the NBAR value at the mean solar zenith angle of the 16 day period. Quality information is replicated and available with each quantity. Every 16 days, the MODIS BRDF/Albedo Product (MOD43B) algorithm relies on multi-date, atmospherically corrected, cloud-cleared data and a semi-empirical kernel-driven bidirectional reflectance model to determine a global set of parameters describing the BRDF of the land surface. These one kilometer gridded parameters are then used to determine directional hemispherical reflectance ("black-sky albedo"), bi-hemispherical reflectance ("white-sky albedo"), and nadir BRDF-adjusted reflectance (NBAR) for seven spectral bands and (in the case of albedo) three broad bands. Since the parameters of the simple kernel-based BRDF model (Ross-Thick/Li-Sparse Reciprocal) are also provided, along with extensive quality information, the MODIS BRDF/Albedo Product offers members of the global observation and modeling community the additional flexibility to derive reflectance and albedo measures particularly suited to their specific applications.
