在进入地球大气层时,微流星体部分或全部消融,留下金属原子和离子层。目前的烧蚀模型不能很好地解释各种金属层的相对浓度。此外,对进入地球大气层的宇宙尘埃和流星体的总通量的估计相差两个数量级以上。为了更好地约束这些估计并更好地模拟中间层中的金属层,开发了一个实验性的大气烧蚀模拟器(MASI)。星际尘埃粒子(IDP)类似物受到温度分布模拟现实的入口加热,以确定相关金属物种的差异烧蚀。MASI是第一个能够模拟详细的质量、速度和进入角度特定温度分布的烧蚀实验,同时以时间分辨的方式跟踪所产生的气相烧蚀产物。这样就可以在考虑国内流离失所者的质量和大小分布的情况下确定进入大气层的元素产量。该仪器还可以在实验室环境中首次直接测量微分烧蚀。
On entering the Earth's atmosphere, micrometeoroids partially or completely ablate, leaving behind layers of metallic atoms and ions. The relative concentration of the various metal layers is not well explained by current models of ablation. Furthermore, estimates of the total flux of cosmic dust and meteoroids entering the Earth's atmosphere vary over two orders of magnitude. To better constrain these estimates and to better model the metal layers in the mesosphere, an experimental Meteoric Ablation Simulator (MASI) has been developed. Interplanetary Dust Particle (IDP) analogs are subjected to temperature profiles simulating realistic entry heating, to ascertain the differential ablation of relevant metal species. MASI is the first ablation experiment capable of simulating detailed mass, velocity, and entry angle-specific temperature profiles whilst simultaneously tracking the resulting gas-phase ablation products in a time resolved manner. This enables the determination of elemental atmospheric entry yields which consider the mass and size distribution of IDPs. The instrument has also enabled the first direct measurements of differential ablation in a laboratory setting.
