Properties of haze in the atmosphere of Triton

Voyager UV spectrometer measurements of CH4 and haze of the Triton atmosphere combined with the haze brightness profile determined by the narrow angle camera are used to infer a haze optical thickness of 0.024 at 1500 A and 0.0078 in the spectral range of the narrow angle camera centered at 4700A, rho/gamma = 0.36 +/- 0.1 g/cu cm (gamma is the quantum yield of condensate), and values of r(c) varying from 0.1 +/- 0.02 micron at 30 km to 0.15 +/- 0.03 micron near the surface. Other auxiliary properties of the haze are also determined. The value found for rho/gamma corresponds to a packing coefficient of 0.6 gamma if C2H4 is the main condensible species.
