Abstract:

An algorithm is described and evaluated for determining the absorption and backscattering coefficients az and bbz from measurements of the nadir-viewing radiance Luz and downward irradiance Edz. The method, derived from radiative transfer theory, is similar to a previously proposed one for Euz and Edz, and both methods are demonstrated with numerical simulations and field data. Numerical simulations and a sensitivity analysis show that good estimates of az and bbz can be obtained if the assumed scattering phase function is approximately correct. In an experiment in Long Island Sound, estimates of az derived with these methods agreed well with those obtained from an in situ reflecting tube instrument.
