The monitoring of the impact of aerosols in Latin America on a local scale isusually limited due to the infrastructure and instrumentation available. InColombia, there are two international ground surface monitoring networks, theAErosol RObotic NETwork (AERONET) and the Latin American LIDAR NETwork(LALINET). However, the AERONET performance relies on only one sun photometerwhich makes measurements distributed among five ground-based stations indifferent cities such as Bogot\'a and Medell\'in. On the other hand, LALINEThas only one ground-based station formed by an elastic LiDAR system located atMedell\'in. Although Cali is the largest city of Colombian southwestern, withan accelerated grown rate of both urban and vehicular fleet, and counts withthe third largest population of this country, is not reached by these networks.Here, we report on the implementation of a monostatic-coaxial multispectralLiDAR system using a pulsed Nd:YAG laser with 450 mJ of average energy at 1064nm. To perform the atmospheric measurements, this system is capable ofspatially resolving elastic backscatter down to 3.75 m with a Pulse RepetitionFrequency (PRF) of 10 Hz. We have developed a hybrid algorithm for dataanalysis by combining the Fitting and Gradient method and the Klett-Fernaldalgorithm to estimate the Planetary Boundary Layer (PBL) Top and the opticalproperties of aerosols. This work constitutes the first quantitativeatmospheric exploration to study the aerosols dynamics and the PBL in thenorthwest of South America.
