Abstract

The Limb Profiler of the Ozone Mapping and Profiler Suite (LP/OMPS) onboard the Suomi spacecraft (NASA/NОАА) has a high sensitivity to the presence of aerosols in the stratosphere and mesosphere at altitudes of 15 to 90 km. Consequently, with this instrument, it is easy to detect, in particular, the Junge aerosol layer and stratospheric and mesospheric polar clouds and atmospheric trails of large bolides. This paper deals with the Suomi limb profiler observations of aerosol trails remaining at altitudes of 30–65 km after rocket launches. In some cases, an aerosol trail of a rocket has been observed for several days, which makes it possible to use these clouds as indicators in the analysis of wind transport in the stratosphere. Sometimes, clouds were observed not only at the launch site, but far from it in the direction of satellite motion. This phenomenon may be caused by the ballistic transport of aerosol clouds: the unburnt particles in the exhaust plume of a carrier rocket, which are formed at altitudes of ~100 km, which have a velocity smaller than the orbital one, but it is high enough for the cloud to pass along the suborbital trajectory and come back to the atmosphere at a distance of thousands of kilometers from the launch site. The effectiveness of observations of aerosol clouds, both natural and artificial, can be enhanced by using a limb profiler with a large number of observational points distributed over the entire horizon.

人造气溶胶云的太空四肢观察

摘要

Suomi航天器（NASA /NОАА）上的臭氧测绘和轮廓仪套件（LP / OMPS）的肢体轮廓仪对15至90 km高度的平流层和中层中的气溶胶存在高度敏感。因此，使用该仪器可以轻松检测到特别是Junge气溶胶层以及平流层和中层的极地云以及大型硫化物的大气迹线。本文涉及Suomi火箭发射后，在30–65 km的高度仍保留有气溶胶踪迹的肢体轮廓观测器。在某些情况下，已经连续几天观察到火箭的气溶胶踪迹，这使得可以将这些云用作平流层风速分析的指标。有时，不仅在发射场观察到云，而且在卫星运动的方向上还观察到很远。这种现象可能是由气溶胶云的弹道运输引起的：运载火箭的排气羽流中未燃烧的颗粒，形成于约100 km的高度，其速度小于轨道运动的速度，但足够高让云沿着亚轨道运动，并返回到距发射场数千公里的大气层。
