Abstract

Aerosol phase function, P^A(χ), is estimated in backscatter (χ>130°) from match-up AVHRR and ship Sun-photometer measurements. The linearized single-scattering approximation for the radiative transfer equation is used, with some adjustments to account approximately for multiple scattering effects. The newly estimated P^A(χ) is in agreement with the phase function of maritime aerosol proposed in the scientific literature. The derived P^A(χ) may be used to constrain the range of its variability in real marine atmosphere, which is important for aerosol retrievals from CZCS, AVHRR, MODIS, MISR, and SeaWiFS
