Scientific Assessment and Evaluation of ASL Developed Moist Atmosphere Models for Low Stratus Subclouds

摘要

The following topics were discussed: 1. Improvement of the formulations for the moist potential temperature and of the water budget equation to be used in A similarity model for moist haze . 2. Introduction of non-equilibrium growth of particles to cloud droplets into the model mentioned above and into the Moist haze microphysics profile model. 3. Simplification of the final particle growth model to allow faster calculations. 4. Use of measured particle growth data for model calculations and derivation of particle growth data from the measured chemical composition of the particles. 5. Introduction of particle concentration profiles into both models. Both models should be brought into final form at first. Secondly sensitivity studies about the aerosol property influences on the extinction and mass loading profiles and more comparisons of the models with available experimental results should be performed. These studies will give more information about the minimum accuracies of the aerosol properties to be measured during field experiments. (sdw)
