SIMULTANEOUS MEASUREMENTS OF TROPOSPHERIC AEROSOLS AND WATER VAPOR VERTICAL PROFILES

Aerosols play an important role in the Earth's radiative balance and in the global climate. They influence the radiation balance either by scattering and absorbing solar radiation, and by acting as cloud condensation nuclei and thus dramatically affecting the optical properties of clouds. Besid...

Description
Summary:Aerosols play an important role in the Earth's radiative balance and in the global climate. They influence the radiation balance either by scattering and absorbing solar radiation, and by acting as cloud condensation nuclei and thus dramatically affecting the optical properties of clouds. Besides aerosols, the water vapor mixing ratio has also an important role in radiation transfer processes, cloud formation, and atmospheric circulation (e.g. Goldsmith et al., 1998). The condensation of water vapor onto aerosol particles significantly affects the particle size, shape, and chemical composition (e.g. Reichardt et al., 1996) and therefore the aerosol role in the radiative forcing of climate. Thus, simultaneous measurements of the vertical profiles of aerosols and water vapor densities allow to investigate the correlation between these two interesting atmospheric parameters and may provide a better understanding of their respective role in the Earth's radiative balance and in the global climate. Simultaneous measurements of the aerosol backscattering ratio and water vapor mixing ratio taken by the UNI-Le lidar operating at the Physics Department of Lecce's University (40 degree 20' N, 18 degree 6' E) are presented in the paper.
