Monitoring of temporal and spatial dynamics of aerosols and clouds by using a portable automated lidar

We have developed and operated a portable automated lidar (PAL) system that is capable of unattended, continuous operation under all-weather conditions. Here we report the features of the observed signals that convey the information on the temporal and spatial dynamics of the aerosols and clouds in the troposphere, illustrating the advantage of the continuous operation through nighttime and daytime.
