Abstract

The lidar device as part of the meteorological complex of the ExoMars-2022 landing platform is designed to study Martian aerosol, the planetary boundary layer, and small-scale atmospheric turbulence. A miniature lidar based on a pulsed semiconductor laser and an avalanche photodiode in the photon counting mode will make it possible to obtain aerosol backscattering profiles along a vertical path from 10 to 1500 m during the day and from 15 to 10 000 m at night. In the passive mode, the sky brightness is measured in a narrow spectral range and in a narrow solid angle with a frequency of up to hundreds of hertz. The measured fluctuations can provide information about the turbulence of the daytime atmosphere and its relation to dust activity. In the paper we considered the scientific tasks of the experiment, the program of measurements on the surface of Mars and described in detail the components of the equipment and the features of their work.

用于从表面调查火星大气的激光雷达

摘要

激光雷达装置是ExoMars-2022气象综合体的一部分着陆平台旨在研究火星气溶胶、行星边界层和小规模大气湍流。基于脉冲半导体激光器和光子计数模式雪崩光电二极管的微型激光雷达将能够沿着垂直路径获取白天10至1500m、夜间15至10000m的气溶胶反向散射剖面。在被动模式下，天空亮度是在窄光谱范围和窄立体角中测量的，频率高达数百赫兹。测量到的波动可以提供有关白天大气湍流及其与灰尘活动的关系的信息。在论文中，我们考虑了实验的科学任务，
