Backscattering by Non-Spherical Natural Particles:Instrument Development, IOP'S, and Implications for Radiative Transfer

Abstract

We have developed the LISST series instruments that provide unprecedented quality of data on the forward scattering of light. In this project, we plan to (a) develop a version of this instrument that will deliver the same high-quality data in backscatter, (b) guide analytical light-scattering model development with such observations, and (c) then apply the results to predicting light propagation in the sea by providing as input, the new estimates of IOP s. This proposal is relevant to ONR s Sensor and Systems and Modeling thrust areas. It will contribute to understanding of how the shape of oceanic particles affect backscattering and provide an instrument that specifically addresses backscattering near 180 degree - a crucial parameter to understand, predict, and invert LIDAR signal. The LIDAR signal is proportional to the VSF near 180 degrees.
