Bimodal Distribution of Sulfuric Acid Aerosols in the Upper Haze of Venus [PDF]

open access: yes, 2013
The upper haze (UH) of Venus is variable on the order of days and it is populated by two particle modes. We use a 1D microphysics and vertical transport model based on the Community Aerosol and Radiation Model for Atmospheres to evaluate whether ...
