Abstract

The lidar applications are widely used for the gaseous molecules ultra low concentration levels in atmosphere as the environmental pollution monitoring. It demands the detail studies of the atmospheric optics basics and computer simulation of the laser sensing possibility in such a molecules detection by the laser radiation with pulse energy up to 35 mJ at the wavelength of 532 nm. The lidar signal of the HF molecule versus the sensing distance have been a subject of the simulation studies of this signal concentration dependence. It takes into account the Sun background radiation as the minimal lidar HF signal and the HF concentration versus distance dependence for these molecules ultra low concentration level in atmosphere. These simulation results show the HF molecules Raman and DAS lidar sensing efficiency for low concentration in the distance range from 1 to 1000 m by chosen laser wavelength and pulse energy in the daytime ranging regime.
