Band

A discrete wavelength interval or range observed by a remote sensing instrument. 

Barest Earth

An estimate of the spectra of the barest state (i.e. least vegetation) observed from imagery of the Australian continent collected by the Landsat 5, 7, and 8 satellites.

Bidirectional Reflectance Distribution Function (BRDF)

A function of four real variables that defines how light is reflected at an opaque surface. It is employed in surface reflectance satellite imagery, computer graphics and vision algorithms.

Bidirectional Reflectance Distribution Function (BRDF) / Albedo Parameter

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).
