Spatially resolved Voyager 2 PPS photometric and polarimetric observations of Neptune at 2650 and 7500 Å are presented and analyzed. A vertically homogeneous model with Rayleigh scattering and absorption fit the 2650 Å at 137° phase and below, but not the 159° phase data. The 159° phase data imply stratospheric particles of mean radius 0.20 ± 0.05 μm, with a best-fit imaginary refractive index at 2650 Å of 0.03. The optical depth of the stratospheric haze in the 5- to 100-mbar region is 0.19 ± 0.08 at 2650 Å. The 7500 Å data at latitude - 25° constrain the stratospheric haze mean radius to be less than 0.4 μm, with a best-fit value of 0.25 μm. Stratospheric haze optical depth at 7500 Å is 0.05 ± 0.02. A continuum absorber is abundant in the troposphere. If it is confined to the region below the methane haze layer, the optical depth of the methane haze can be no larger than about 0.8 (too much limb brightening is produced for larger optical depths). The methane haze optical depth at 7500 Å must be greater than 0.1. Models with this optical depth as large as 3 produced too much limb darkening if the continuum absorber is mixed in both the methane haze and deeper cloud. Tropospheric aerosols have phase functions with shalloow backward lobes, described by a double Henyey-Greenstein parameterization with g 2 (the asymmetry parameter for the backward lobe) in the range −0.07 to −0.22. The planetary phase integral (the ratio of the spherical albedo to the geometric albedo) at 7500 Å is 1.4 ± 0.1; at 2650 Å it is 1.26 ± 0.05.
