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.
