The multimodal microstructure of the Venus cloud system has been examined. In addition to confirmed H(2)SO(4) droplets and suspected elemental sulfur, a highly concentrated aerosol population has been observed extending above, within, and below the cloud system. These aerosols appear to cycle through the cloud droplets, but can never be removed by the weak precipitation mechanisms present. All cloud particles are likely laced with aerosol contaminants. Sedimentation and decomposition of H(2)SO(4) in the droplets of the lower cloud region contribute more than 7 watts per square meter of heat flux equaling one-fourth of the solar net flux at 50 kilometers.
金星云系统的多模态微观结构已经过检查。除了已确认的 H(2)SO(4)液滴和疑似单质硫之外，还观察到在云系统上方、内部和下方延伸的高度集中的气溶胶群体。这些气溶胶似乎在云滴中循环，但目前存在的弱降水机制永远无法将其清除。所有云粒子都可能带有气溶胶污染物。硫酸(H(2)SO(4))在较低云层区域的液滴中的沉降和分解产生的热通量超过 7 瓦/平方米，相当于 50 公里处太阳能净通量的四分之一。
