| This work presents the implementation of a multi-wavelength Lidar system at the UPRM (University of Puerto Rico at Mayaguez) located at the western region of the island of Puerto Rico. The UPRM-Lidar system is situated close to the coastal region where sea-salt particles and mountains play an important role in cloud formation. Remote measurements with this system provide vertical and horizontal remote sensing information of backscatter and extinction coefficient of aerosol, cirrus clouds, upper troposphere, PBL (Planetary Boundary Layer), and other events such as: Saharan dust, smoke, volcano haze, etc.;The UPRM-Lidar system is based on the laser transmission wavelengths of 355, 532, and 1064nm and the detection of elastic backscatter light (same wavelengths). Profiles of backscatter and extinction coefficients of aerosols and clouds at different heights are obtained using algorithms developed in this research to determine the aerosols size distributions, particle matter concentrations, air quality indices, and others. |
