摘要
In the Universidad Nacional de Colombia, Sede Medellin, the Lasers and Spectroscopy Group （GLEO） has been designed and manufactured a tropospheric lidar station based on a pulsed Nd：YAG laser operating at 532-nm wavelength. The main scientific objective has been to evaluate the vertical structure of the Planetary Boundary Layer （PBL） in urban sites of Medellin-Colombia, South America, （Longitude 75°34′05″ West, Latitude 6°13′55″ North）, using suspended aerosols as tracers of the atmospheric motion. This paper reports the design, manufactures and performance of an elastic lidar system, which was operated under varying air pollution and meteorological conditions and the observations presented here were performed in early 2010, over the metropolitan area of Medellin, city included in the Andean region of Colombia.
