Abstract

Since 1996 a lidar station is operated routinely at CEILAP (CITEFA-CONTCET), located in Buenos Aires suburb. The scientific objectives are related to environmental and atmospheric radiative budget studies. Two backscatter lidars operating at 532 nm and 308 nm are used to document the atmospheric boundary layer dynamics, and cirrus clouds and tropospheric aerosols radiative properties. The lidar measurements are made in conjuction with visible radiometer measurements on the same site and radiosoundings made twice daily at the nearby meteorological station. Atmospheric boundary layer measurements during daytime are conducted since 1996 on a regular basis using the backscatter lida.r operating at 532 nm, and more recently using a second lidar on the same site operating at 308 nm. Similarly, cirrus clouds and tropospheric aerosols measurements are conducted during clear days (e.g. without low clouds) since 1996 using the backscatter lidars. Since the late 1997 more interest is given to urban ABL dynamics in connection with pollution events, and biomass burning taking place in the tropical South America. It happened that such plumes can be frequently transported over the Buenos Aires area by large scale circulation
