Recent advances in interplanetary dust modelling provide much improved estimates of the fluxes of cosmic dust particles into planetary (and lunar) atmospheres throughout the solar system. Combining the dust particle size and velocity distributions with new chemical ablation models enables the injection rates of individual elements to be predicted as a function of location and time. This information is essential for understanding a variety of atmospheric impacts, including: the formation of layers of metal atoms and ions; meteoric smoke particles and ice cloud nucleation; perturbations to atmospheric gas-phase chemistry; and the effects of the surface deposition of micrometeorites and cosmic spherules. There is discussion of impacts on all the planets, as well as on Pluto, Triton and Titan.

宇宙尘埃对行星大气和表面的影响

行星际尘埃建模的最新进展大大改进了对整个太阳系中进入行星（和月球）大气的宇宙尘埃粒子通量的估计。将灰尘颗粒大小和速度分布与新的化学烧蚀模型相结合，可以将单个元素的注入率预测为位置和时间的函数。这些信息对于了解各种大气影响至关重要，包括： 金属原子和离子层的形成；大气烟雾颗粒和冰云成核；对大气气相化学的扰动；以及微陨石和宇宙小球表面沉积的影响。讨论了对所有行星以及冥王星、海卫一和泰坦的影响。
