A general two-stream algorithm for retrieving spectral surface albedo

Spectral surface albedo (SSA) has numerous applications in climate and environmental studies. Given that ground-based observations of SSA are very limited, space-borne remote sensing has been the primary means of acquiring SSA on large or global scales. To date, many satellite sensors measure reflectances in different spectral regions from which values of SSA are inferred. The inversion algorithms range from simple linear relationships to …
