Abstract

The investigation reported in this dissertation has been divided in two parts. The first part was made to carry out an independent calibration of a Raman lidar system for water vapor in the CLA installed using a methodology that was developed at Howard University, based on a careful analysis of the efficiency of the optical system components aimed at determining the efficiency and displaying the spectral response of the system. After this study, which led to a better understanding of the field of instrumental system, the second part, presents a preliminary study of the optical properties of aerosols in the troposphere by evaluating parameters such as, for example, the vertical proles of aerosol extinction, SR and LR, using a mobile Raman LIDAR system developed by Raymetrics Lidar Systems, during campaigns conducted in some research institutes in the State of São Paulo.
