Abstract

In the practice of aerological sounding, along with lidar observations, aerosol backscattering sondes are used at night to study and monitor polar stratospheric clouds, tropospheric and stratospheric aerosol, cirrus clouds, pyroconvection, and volcanic aerosol, as well as to verify remote methods and means of ground-based and satellite-based aerosol observations. For aerosol sondes, a simple two-wave measurement technique is used, which makes it possible to diagnose changes in aerosol composition by color index. There are limitations to the possibilities of the two-wave technique, and they are discussed in this article. Aerological sounding combined with lidar observations expands the wavelength range for multiwavelength studies, and direct measurements of atmospheric temperature increase the accuracy of aerosol sensing. This paper considers the application of three or more wavelength techniques. Data from probe measurements using wavelengths of 470, 528, 850, and 940 nm and lidar sensing at wavelengths of 355 and 532 nm are presented.

关于多通道光学反向散射探测仪用于气球和激光雷达联合研究中层大气气溶胶成分的可能性

摘要在空气探测实践中，气溶胶后向散射探空仪与激光雷达观测一起用于夜间研究和监测极地平流层云、对流层和平流层气溶胶、卷云、热对流和火山气溶胶，以及验证地面和卫星气溶胶观测的遥感方法和手段。气溶胶探测仪使用简单的双波测量技术，可以通过颜色指数诊断气溶胶成分的变化。本文将讨论双波技术的局限性。空气探测与激光雷达观测相结合，扩大了多波长研究的波长范围，对大气温度的直接测量提高了气溶胶传感的准确性。本文考虑了三种或更多波长技术的应用。文中介绍了使用波长为 470、528、850 和 940 纳米的探测器测量数据，以及使用波长为 355 和 532 纳米的激光雷达传感数据。
