Ground-based remote sensing of the atmosphere is of critical importance for both long and short term global climate change analysis. The UPRM Lidar system functions in this capacity, using the elastic backscatter of 355, 532, and 1064 nm channels to provide real aerosol characterization over the Mayaguez, Puerto Rico region, a dynamic area in the tropics subject to varied phenomena such as Saharan dust which influence local and global climate. Calculation of the aerosol optical depth (AOD) and Aerosol Size Distribution (ASD) from the received signal, in conjunction with validation with AERONET allows for aerosol microphysical property studies. The Planet Boundary Layer (PBL) depth and regional Air Quality Index (AQI) are determined and presented in this research work. A study of sensors correlations is presented showing the particle sizes mixture detection sensitivity of the three UPRM Lidar wavelengths.
