Abstract
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.
