The Effects of Aerosol on Small-Scale Cloud-Environment Mixing: Implications for Observing Inhomogeneous Mixing

This is the simulation output of the submitted manuscript "The Effects of Aerosol on Small-Scale Cloud-Environment Mixing: Implications for Observing Inhomogeneous Mixing" to the Journal of Geophysical Research: Atmospheres. Abstract: The mixing of clouds with their environment can change the size and number of cloud droplets, two important parameters to understand the role of clouds in the climate system. Because these changes are determined by the way a cloud mixes with its environment, they have been used to characterize the mixing process. Using a highly detailed numerical cloud model coupled with a statistical turbulence model, we show that the adequate consideration of aerosol particles from which cloud droplets grow, can alter the changes of cloud droplets during mixing. This has not been considered in the past. We identify biases that need to be considered when mixing processes are analyzed. The raw data presented here was produced by the aforementioned model only and is completely available.本数据集为投稿至《地球物理研究杂志：大气（Journal of Geophysical Research: Atmospheres）》的手稿"《气溶胶对小尺度云-环境混合过程的影响：非均匀混合观测的启示》"的模拟输出结果。摘要：云与其环境气团的混合过程会改变云滴的粒径与数浓度，二者是理解云在气候系统中作用的核心参数。由于此类变化由云与环境的混合方式决定，因此可通过该变化表征混合过程的特征。本研究采用耦合了统计湍流模型（statistical turbulence model）的精细化数值云模式（numerical cloud model），结果证实，充分考虑云滴形成所依托的气溶胶粒子，能够改变混合过程中云滴的相关变化——这一关键因素在过往研究中未被纳入考量。本研究明确了分析混合过程时需考量的各类偏差。本文所提供的原始数据仅由上述数值模式生成，且完全公开可获取。
