摘要

摘要我们已经评估了带有瞬态记录器的气溶胶激光雷达装置可能的干扰源。这是通过两种方法完成的：对激光雷达信号进行频谱分析以检测射频干扰和测量激光电源引起的电磁干扰。我们在瞬态记录器的模拟通道中发现了干扰，可能是由旧记录器的老化效应引起的。回顾性地提出了一种简单的方法来提高信噪比。我们还表明，在我们的位置使用双向无线电会导致激光雷达轮廓中出现明显的射频干扰。此外，我们还对激光电源引起的电磁干扰进行了测量，如果瞬态记录器放在激光雷达附近，可能会导致激光雷达轮廓的干扰。

Influence of electromagnetic interference on the evaluation of lidar-derived aerosol properties from Ny-Ålesund, Svalbard

Abstract. Possible interference sources for our aerosol lidar setup with transient recorders have been assessed. This was done by two methods: a spectrum analysis of the lidar signals in order to detect radio-frequency interference and measurements of the electromagnetic interference caused by the laser power supply. We found disturbances in the analog channels of the transient recorders, presumably caused by aging effects of our older recorders. An easy method on how the signal-to-noise ratio can be improved retrospectively is presented. We also show that the usage of two-way radio at our location leads to a noticeable radio-frequency interference in the lidar profiles. Further, we present measurements of the electromagnetic interference caused by the laser power supply, which may lead to disturbances in the lidar profiles if the transient recorders are placed next to it.

期刊介绍： Atmospheric Measurement Techniques (AMT) is an international scientific journal dedicated to the publication and discussion of advances in remote sensing, in-situ and laboratory measurement techniques for the constituents and properties of the Earth’s atmosphere. The main subject areas comprise the development, intercomparison and validation of measurement instruments and techniques of data processing and information retrieval for gases, aerosols, and clouds. The manuscript types considered for peer-reviewed publication are research articles, review articles, and commentaries.
