Abstract
Some improvements are introduced into the haze model by Krasnopolsky e t al. (1992), which describes growth and precipitation of particles fo rmed by methane photolysis. These improvements take into account a pos sible termination of the Voyager Ultraviolet Spectrometer (UVS) occult ation observations by clouds and a more accurate presentation of the s urface reflection by a modified Hapke function. All changes we within the uncertainties of the previous model, though not negligible. The pa rticle mean radius and number density for global mean conditions vary from 0.1+/-0.01 mum and 2.4 cm-3 at 30 km to 0.135+/-0.015 mum and 10. 4 cm-3 near the surface. The scale height of the volume extinction coe fficient in the visible varies from 7 km at h=25 km to 15 km at h=5 km . The vertical optical thickness of haze is equal to (5+/-1)x10(-3) at 0.47 mum.
