Transmissometers always accept a certain portion of the forward-scattered light. The error in the beam-attenuation coefficient c(λ) due to this acceptance varies with the small-angle scattering function, single-scattering albedo, and instrumental design. This paper details methods to model error in measurements of c(λ) obtained with cylindrically limited and collimated-beam transmissometers. These models are used with real examples of beam attenuation and small-angle scattering function data to test how this measurement error varies. -Authors
