Abstract

Recently a low cost portable lidar system has been developed at the National Atmospheric Research Laboratory (NARL), Gadanki (13.5°N, 79.2°E), India for profiling the atmospheric aerosol and clouds. The lidar system utilizes state-of-the-art technology with a high repetition rate, low pulse energy diode pumped Nd:YAG laser and photon-counting detection, which considered to be first of its kind in India. The lidar system measures the laser backscattered radiation from aerosols and molecules at 532 nm that provide information on the height profiles of aerosols, boundary layer mixing height, cloud base height and cloud vertical extent. The system is capable of continuous, autonomous data acquisition in both daytime and nighttime. The lidar range go up to 3-4 km during daytime, where as its visibility extends to the end of troposphere during nighttimes.
