The fraction of beam attenuation due to scattering rather than absorption, \(\omega_0 = b / (a + b) = b / c\) (Johnsen 2012, ch. 5). Values near 1 indicate a strongly scattering, weakly absorbing medium (e.g. fog or milk); values near 0 a strongly absorbing one.

Usage

single_scattering_albedo(absorption, scattering)

Arguments

absorption

Absorption coefficient \(a\) (1/m). Vectorised.

scattering

Scattering coefficient \(b\) (1/m). Vectorised.

Value

Single-scattering albedo \(\omega_0\) (dimensionless, 0-1).
