The LATMOS Venus cloud model VenLA (Venus Liquid Aerosols) is based on a terrestrial Polar Strato-spheric Cloud (PSC) model [7]. VenLA models the formation, growth and decay of sulfuric acid-water droplets. The model has undergone several updates. We will present results of reference runs and sensitivity tests based on input profiles from VIRA [5] for temperature and pressure and from occultation data concerning the vapors, as in [8]. We compare the results to the available observations on cloud particle number densities and sizes, and to other modeling studies. The VenLA model will define the baseline for a parallel project on development of a moment method scheme to be used in a global climate model (see abstract Guil-bon et al., this conference [2]).
