文摘

Angularly and spectrally resolved BRDF from snow was measured using a near-infrared spectrometer. Estimated coefficients of the phase function properly capture the spectral and angular features of snow. The first Legendre coefficient corresponds to the single scattering albedo. The second Legendre coefficient corresponds to the asymmetry parameter.
